SPNS155F – SEPTEMBER 2009 – REVISED AUGUST 2012
DESCRIPTION
The SM470R1B1M (1) devices are members of the Texas Instruments SM470R1x family of general-purpose
16/32-bit reduced instruction set computer (RISC) microcontrollers. The B1M microcontroller offers high
performance utilizing the high-speed ARM7TDMI 16/32-bit RISC central processing unit (CPU), resulting in a
high instruction throughput while maintaining greater code efficiency. The ARM7TDMI 16/32-bit RISC CPU views
memory as a linear collection of bytes numbered upwards from zero. The SM470R1B1M utilizes the big-endian
format where the most significant byte of a word is stored at the lowest numbered byte and the least significant
byte at the highest numbered byte.
High-end embedded control applications demand more performance from their controllers while maintaining low
costs. The B1M RISC core architecture offers solutions to these performance and cost demands while
maintaining low power consumption.
The B1M devices contain the following:
• ARM7TDMI 16/32-Bit RISC CPU
• SM470R1x system module (SYS) with 470+ enhancements
• 1M-byte flash
• 64K-byte SRAM
• Zero-pin phase-locked loop (ZPLL) clock module
• Digital watchdog (DWD) timer
• Analog watchdog (AWD) timer
• Enhanced real-time interrupt ( RTI) module
• Interrupt expansion module (IEM)
• Memory security module (MSM)
• JTAG security module
• Two serial peripheral interface (SPI) modules
• Three serial communications interface (SCI) modules
• Two high-end CAN controllers (HECC)
• Five inter-integrated circuit (I2C) modules
• 10-bit multi-buffered analog-to-digital converter (MibADC), with 12 input channels
• High-end timer lite (HET) controlling 12 I/Os
• External clock prescale (ECP)
• Expansion bus module (EBM)
• Up to 93 I/O pins
The functions performed by the 470+ system module (SYS) include:
• Address decoding
• Memory protection
• Memory and peripherals bus supervision
• Reset and abort exception management
• Prioritization for all internal interrupt sources
• Device clock control
• Parallel signature analysis (PSA)
The enhanced real-time interrupt (RTI) module on the B1M has the option to be driven by the oscillator clock.
The digital watchdog (DWD) is a 25-bit resettable decrementing counter that provides a system reset when the
watchdog counter expires. This data sheet includes device-specific information such as memory and peripheral
select assignment, interrupt priority, and a device memory map. For a more detailed functional description of the
SYS module, see the TMS470R1x System Module Reference Guide (literature number SPNU189).
The B1M memory includes general-purpose SRAM supporting single-cycle read/write accesses in byte, halfword, and word modes.

SPNS155F – SEPTEMBER 2009 – REVISED AUGUST 2012

The flash memory on this device is a nonvolatile, electrically erasable and programmable memory implemented
with a 32-bit-wide data bus interface. The flash operates with a system clock frequency of up to 24 MHz or 30
MHz, depending on the input voltage. When in pipeline mode, the flash operates with a system clock frequency
of up to 48 MHz or 60 MHz, depending on the input voltage. For more detailed information on the flash, see the
F05 Flash section of this data sheet.
The memory security module (MSM) and the JTAG security module prevent unauthorized access and visibility to
on-chip memory, thereby preventing reverse engineering or manipulation of proprietary code.
The B1M device has twelve communication interfaces: two SPIs, three SCIs, two HECCs, and five I2Cs. The SPI
provides a convenient method of serial interaction for high-speed communications between similar shift-register
type devices. The SCI is a full-duplex, serial I/O interface intended for asynchronous communication between the
CPU and other peripherals using the standard non-return-to-zero (NRZ) format. The HECC uses a serial,
multimaster communication protocol that efficiently supports distributed real-time control with robust
communication rates of up to 1 megabit per second (Mbps). These CAN peripherals are ideal for applications
operating in noisy and harsh environments (e.g., industrial fields) that require reliable serial communication or
multiplexed wiring. The I2C module is a multi-master communication module providing an interface between the
B1M microcontroller and an I2C-compatible device via the I2C serial bus. The I2C supports both 100 Kbps and
400 Kbps speeds. For more detailed functional information on the SPI, SCI, and CAN peripherals, see the
specific reference guides (literature numbers SPNU195, SPNU196, and SPNU197). For more detailed functional
information on the I2C, see the TMS470R1x Inter-Integrated Circuit (I2C) Reference Guide (literature number
SPNU223).
The HET is an advanced intelligent timer that provides sophisticated timing functions for real-time applications.
The timer is software-controlled, using a reduced instruction set, with a specialized timer micromachine and an
attached I/O port. The HET can be used for compare, capture, or general-purpose I/O. It is especially well suited
for applications requiring multiple sensor information and drive actuators with complex and accurate time pulses.
The HET used in this device is the high-end timer lite. It has fewer I/Os than the usual 32 in a standard HET. For
more detailed functional information on the HET, see the TMS470R1x High-End Timer (HET) Reference Guide
(literature number SPNU199).
The B1M HET peripheral contains the XOR-share feature. This feature allows two adjacent HET high-resolution
channels to be XORed together, making it possible to output smaller pulses than a standard HET. For more
detailed information on the HET XOR-share feature, see the TMS470R1x High-End Timer (HET) Reference
Guide (literature number SPNU199).
The B1M device has one 10-bit-resolution, sample-and-hold MibADC. Each of the MibADC channels can be
converted individually or can be grouped by software for sequential conversion sequences. There are three
separate groupings, two of which can be triggered by an external event. Each sequence can be converted once
when triggered or configured for continuous conversion mode. For more detailed functional information on the
MibADC, see the TMS470R1x Multi-Buffered Analog-to-Digital Converter (MibADC) Reference Guide (literature
number SPNU206).
The zero-pin phase-locked loop (ZPLL) clock module contains a phase-locked loop, a clock-monitor circuit, a
clock-enable circuit, and a prescaler (with prescale values of 1–8). The function of the ZPLL is to multiply the
external frequency reference to a higher frequency for internal use. The ZPLL provides ACLK to the system
(SYS) module. The SYS module subsequently provides system clock (SYSCLK), real-time interrupt clock
(RTICLK), CPU clock (MCLK), and peripheral interface clock (ICLK) to all other B1M device modules. For more
detailed functional information on the ZPLL, see the TMS470R1x Zero-Pin Phase-Locked Loop (ZPLL) Clock
Module Reference Guide (literature number SPNU212).
NOTE
ACLK should not be confused with the MibADC internal clock, ADCLK. ACLK is the
continuous system clock from an external resonator/crystal reference.
The expansion bus module (EBM) is a standalone module that supports the multiplexing of the GIO functions
and the expansion bus interface. For more information on the EBM, see the TMS470R1x Expansion Bus Module
(EBM) Reference Guide (literature number SPNU222).

The B1M device also has an external clock prescaler (ECP) module that when enabled, outputs a continuous
external clock (ECLK) on a specified GIO pin. The ECLK frequency is a user-programmable ratio of the
peripheral interface clock (ICLK) frequency. For more detailed functional information on the ECP, see the
TMS470R1x External Clock Prescaler (ECP) Reference Guide (literature number SPNU202).

Any pins marked as NC are physically connected to ground internal to the package. Care must be used to keep these pins in a high
impedance input state.

memory selects
Memory selects allow the user to address memory arrays (i.e., flash, RAM, and HET RAM) at user-defined
addresses. Each memory select has its own set (low and high) of memory base address registers (MFBAHRx
and MFBALRx) that, together, define the array's starting (base) address, block size, and protection.
The base address of each memory select is configurable to any memory address boundary that is a multiple of
the decoded block size. For more information on how to control and configure these memory select registers, see
the bus structure and memory sections of the TMS470R1x System Module Reference Guide (literature number
SPNU189).
For the memory selection assignments and the memory selected, see Table 5.

x8 refers to size of memory in 8-bits; x16 refers to size of memory in 16-bits.
The starting addresses for both RAM memory-select signals cannot be offset from each other by a multiple of the user-defined block
size in the memory-base address register.
JTAG security module
The B1M device includes a JTAG security module to provide maximum security to the memory contents. The
visible unlock code can be in the OTP sector or in the first bank of the user-programmable memory. For the
B1M, the visible unlock code is in the OTP sector at address 0x0000_01F8.
memory security module
The B1M device also includes a memory security module (MSM) to provide additional security and flexibility to
the memory contents' protection. The password for unlocking the MSM is located in the four words just before
the flash protection keys.
RAM
The B1M device contains 64K-bytes of internal static RAM configurable by the SYS module to be addressed
within the range of 0x0000_0000 to 0xFFE0_0000. This B1M RAM is implemented in one 64K-byte array
selected by two memory-select signals. This B1M configuration imposes an additional constraint on the memory
map for RAM; the starting addresses for both RAM memory selects cannot be offset from each other by the
multiples of the size of the physical RAM (i.e., 64K bytes for the B1M device). The B1M RAM is addressed
through memory selects 2 and 3.
The RAM can be protected by the memory protection unit (MPU) portion of the SYS module, allowing the user
finer blocks of memory protection than is allowed by the memory selects. The MPU is ideal for protecting an
operating system while allowing access to the current task. For more detailed information on the MPU portion of
the SYS module and memory protection, see the memory section of the TMS470R1x System Module Reference
Guide (literature number SPNU189).

F05 Flash
The F05 flash memory is a nonvolatile electrically erasable and programmable memory implemented with a 32bit-wide data bus interface. The F05 flash has an external state machine for programming and erase functions.
See the Flash read and Flash program and erase sections.
flash protection keys
The B1M device provides flash protection keys. These four 32-bit protection keys prevent
program/erase/compaction operations from occurring until after the four protection keys have been matched by
the CPU loading the correct user keys into the FMPKEY control register. The protection keys on the B1M are
located in the last 4 words of the first 64K sector.
flash read
The B1M flash memory is configurable by the SYS module to be addressed within the range of 0x0000_0000 to
0xFFE0_0000. The flash is addressed through memory selects 0 and 1.
NOTE
The flash external pump voltage (VCCP) is required for all operations (program, erase, and
read).
flash pipeline mode
When in pipeline mode, the flash operates with a system clock frequency of up to 60 MHz (versus a system
clock frequency of 30 MHz in normal mode). Flash in pipeline mode is capable of accessing 64-bit words and
provides two 32-bit pipelined words to the CPU. Also, in pipeline mode the flash can be read with no wait states
when memory addresses are contiguous (after the initial 1- or 2-wait-state reads).
NOTE
After a system reset, pipeline mode is disabled (ENPIPE bit [FMREGOPT.0] is a 0). In
other words, the B1M device powers up and comes out of reset in non-pipeline mode.
Furthermore, setting the flash configuration mode bit (GBLCTRL.4) will override pipeline
mode.

The minimum size for an erase operation is one sector. The maximum size for a program operation is one 16-bit
word.
NOTE
The flash external pump voltage (VCCP) is required for all operations (program, erase, and
read).
Execution can occur from one bank while programming/erasing any or all sectors of another bank. However,
execution cannot occur from any sector within a bank that is being programmed or erased.
NOTE
When the OTP sector is enabled, the rest of flash memory is disabled. The OTP memory
can only be read or programmed from code executed out of RAM.
HET RAM
The B1M device contains HET RAM. The HET RAM has a 64-instruction capability. The HET RAM is
configurable by the SYS module to be addressed within the range of 0x0000_0000 to 0xFFE0_0000. The HET
RAM is addressed through memory select 4.

peripheral selects and base addresses
The B1M device uses 10 of the 16 peripheral selects to decode the base addresses of the peripherals. These
peripheral selects are fixed and transparent to the user since they are part of the decoding scheme used by the
SYS module.
Control registers for the peripherals, SYS module, and flash begin at the base addresses shown in Table 6.

direct-memory access (DMA)
The direct-memory access (DMA) controller transfers data to and from any specified location in the B1M memory
map (except for restricted memory locations like the system control registers area). The DMA manages up to 16
channels, and supports data transfer for both on-chip and off-chip memories and peripherals. The DMA controller
is connected to both the CPU and peripheral buses, enabling these data transfers to occur in parallel with CPU
activity and thus maximizing overall system performance.
Although the DMA controller has two possible configurations, for the B1M device, the DMA controller
configuration is 32 control packets and 16 channels.
For the B1M DMA request hardwired configuration, see Table 7.

DMA CHANNEL
EBM
DMAREQ[13]
For DMA channels with more than one assigned request source, only one of the sources listed can be the DMA request generator in a
given application. The device has software control to ensure that there are no conflicts between requesting modules.
Each channel has two control packets attached to it, allowing the DMA to continuously load RAM and generate
periodic interrupts so that the data can be read by the CPU. The control packets allow for the interrupt enable,
and the channels determine the priority level of the interrupt.
DMA transfers occur in one of two modes:
• Non-request mode (used when transferring from memory to memory)
• Request mode (used when transferring from memory to peripheral)
For more detailed functional information on the DMA controller, see the TMS470R1x Direct Memory Access
(DMA) Controller Reference Guide (literature number SPNU194).

interrupt priority (IEM to CIM)
Interrupt requests originating from the B1M peripheral modules (i.e., SPI1 or SPI2; SCI1 or SCI2; RTI; etc.) are
assigned to channels within the 48-channel interrupt expansion module (IEM) where, via programmable register
mapping, these channels are then mapped to the 32-channel central interrupt manager (CIM) portion of the SYS
module.
Programming multiple interrupt sources in the IEM to the same CIM channel effectively shares the CIM channel
between sources.
The CIM request channels are maskable so that individual channels can be selectively disabled. All interrupt
requests can be programmed in the CIM to be of either type:
• Fast interrupt request (FIQ)
• Normal interrupt request (IRQ)
The CIM prioritizes interrupts. The precedences of request channels decrease with ascending channel order in
the CIM (0 [highest] and 31 [lowest] priority). For IEM-to-CIM default mapping, channel priorities, and their
associated modules, see Table 8.

expansion bus module (EBM)
The expansion bus module (EBM) is a standalone module used to bond out both general-purpose input/output
pins and expansion bus interface pins. This module supports the multiplexing of the GIO and the expansion bus
interface functions. The module also supports 8- and 16- bit expansion bus memory interface mappings as well
as mapping of the following expansion bus signals:
• 27-bit address bus (EBADDR[26:0] for x8, 19-bit address bus (EBADDR[18:0] for x16
• 8- or 16-bit data bus (EBDATA[7:0] or EBDATA[15:0])
• 2 write strobes (EBWR[1:0])
• 2 memory chip selects (EBCS[6:5])
• 1 output enable (EBOE)
• 1 external hold signal for interfacing to slow memories (EBHOLD)
• 1 DMA request line (EBDMAREQ[0])
Table 9 shows the multiplexing of I/O signals with the expansion bus interface signals. The mapping of these
pins varies depending on the memory mode.

MibADC
The multi-buffered analog-to-digital converter (MibADC) accepts an analog signal and converts the signal to a
10-bit digital value.
The B1M MibADC module can function in two modes: compatibility mode, where its programmer's model is
compatible with the SM470R1x ADC module and its digital results are stored in digital result registers; or in
buffered mode, where the digital result registers are replaced with three FIFO buffers, one for each conversion
group [event, group1 (G1), and group2 (G2)]. In buffered mode, the MibADC buffers can be serviced by
interrupts or by the DMA.
MibADC event trigger enhancements
The MibADC includes two major enhancements over the event-triggering capability of the SM470R1x ADC.
• Both group 1 and the event group can be configured for event-triggered operation, providing up to two eventtriggered groups.
• The trigger source and polarity can be selected individually for both group1 and the event group from the
options identified in Table 11.

For group1, these event-triggered selections are configured via the group 1 source select bits (G1SRC[1:0]) in
the AD event source register (ADEVTSRC[5:4]). For the event group, these event-triggered selections are
configured via the event group source select bits (EVSRC[1:0]) in the AD event source register
(ADEVTSRC[1:0]).
For more detailed functional information on the MibADC, see the TMS470R1x Multi-Buffered Analog-to-Digital

Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP
devices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS
(e.g., TMS470R1B1M). Texas Instruments recommends two of three possible prefix designators for its support
tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering
prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
TMX Experimental device that is not necessarily representative of the final device's electrical specifications
TMP Final silicon die that conforms to the device's electrical specifications but has not completed quality and
reliability verification
SM
Fully qualified production device
Support tool development evolutionary flow:
TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing.
TMDS Fully qualified development-support product
TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliability
of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system because their
expected end-use failure rate still is undefined. Only qualified production devices are to be used.
Figure 4 illustrates the numbering and symbol nomenclature for the SM470R1x family.

Source currents (out of the device) are negative while sink currents (into the device) are positive.
The typical values indicated in this table are the expected values during operation under normal operating conditions: nominal VCC,
VCCIO, or VCCAD, room temperature.
This does not apply to the PORRST pin. For PORRST exceptions, see the RST and PORRST Timings section.
These values help to determine the external RC network circuit. For more details, see the TMS470R1x System Module Reference Guide
(literature number SPNU189).
VOL and VOH are linear with respect to the amount of load current (IOL/IOH) applied.
Parameter does not apply to input-only or output-only pins.
Some of the 2 mA buffers on this device are zero-dominant buffers, as indicated by a -z in the Output Current column of the Terminal
Functions table. If two of these buffers are shorted together and one is outputting a low level and the other is outputting a high level, the
resulting value will always be low.

External Reference Resonator/Crystal Oscillator Clock Option
The oscillator is enabled by connecting the appropriate fundamental 4–10 MHz resonator/crystal and load
capacitors across the external OSCIN and OSCOUT pins as shown in Figure 8 (a). The oscillator is a singlestage inverter held in bias by an integrated bias resistor. This resistor is disabled during leakage test
measurement and HALT mode. TI strongly encourages each customer to submit samples of the device to
the resonator/crystal vendors for validation. The vendors are equipped to determine what load capacitors will
best tune their resonator/crystal to the microcontroller device for optimum start-up and operation over
temperature/voltage extremes. Please note that external crystal mode is guaranteed to function only within
the temperature ranges of -40°C to 150°C. Above this recommended temperature range it is strongly
recommended to use an external clock signal as shown in Figure 8 (b).
An external oscillator source can be used by connecting a 1.8-V clock signal to the OSCIN pin and leaving the
OSCOUT pin unconnected (open) as shown in Figure 8b.

f(SYS) = M × f(OSC)/R, where M = {8}, R = {1,2,3,4,5,6,7,8} when PLLDIS = 0. R is the system-clock divider determined by the
CLKDIVPRE [2:0] bits in the global control register (GLBCTRL[2:0]) and M is the PLL multiplier determined by the MULT4 bit also in the
GLBCTRL register (GLBCTRL.3).
f(SYS) = f(OSC)/R, where R = {1,2,3,4,5,6,7,8} when PLLDIS = 1.
f(ICLK) = f(SYS)/X, where X = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}. X is the interface clock divider ratio determined by the PCR0[4:1]
bits in the SYS module.
f(ECLK) = f(ICLK)/N, where N = {1 to 256}. N is the ECP prescale value defined by the ECPCTRL[7:0] register bits in the ECP module.
Only ZPLL mode is available. FM mode must not be turned on.
Pipeline mode enabled or disabled is determined by the ENPIPE bit (FMREGOPT.0).
Flash Vread must be set to 5 V to achieve maximum system clock frequency.
Operating VCC range for this system clock frequency is 1.81 to 2.05 V.

HIGH-END TIMER (HET) TIMINGS
Minimum PWM Output Pulse Width:
This is equal to one high resolution clock period (HRP). The HRP is defined by the 6-bit high resolution prescale
factor (hr), which is user defined, giving prescale factors of 1 to 64, with a linear increment of codes.
Therefore, the minimum PWM output pulse width = HRP(min) = hr(min)/SYSCLK = 1/SYSCLK
For example, for a SYSCLK of 30 MHz, the minimum PWM output pulse width = 1/30 = 33.33ns
Minimum Input Pulses that Can Be Captured:
The input pulse width must be greater or equal to the low resolution clock period (LRP), i.e., the HET loop (the
HET program must fit within the LRP). The LRP is defined by the 3-bit loop-resolution prescale factor (lr), which
is user defined, with a power of 2 increment of codes. That is, the value of lr can be 1, 2, 4, 8, 16, or 32.
Therefore, the minimum input pulse width = LRP(min) = hr(min) * lr(min)/SYSCLK = 1 * 1/SYSCLK
For example, with a SYSCLK of 30 MHz, the minimum input pulse width = 1 * 1/30 = 33.33 ns
NOTE
Once the input pulse width is greater than LRP, the resolution of the measurement is still
HRP. (That is, the captured value gives the number of HRP clocks inside the pulse.)
Abbreviations:
hr = HET high resolution divide rate = 1, 2, 3,...63, 64
lr = HET low resolution divide rate = 1, 2, 4, 8, 16, 32
High resolution clock period = HRP = hr/SYSCLK
Loop resolution clock period = LRP = hr*lr/SYSCLK

MULTI-BUFFERED A-TO-D CONVERTER (MibADC)
The multi-buffered A-to-D converter (MibADC) has a separate power bus for its analog circuitry that enhances
the A-to-D performance by preventing digital switching noise on the logic circuitry, which could be present on V
SS and V CC , from coupling into the A-to-D analog stage. All A-to-D specifications are given with respect to AD
REFLO unless otherwise noted.
