32-bit Power Architecture® Microcontrollers for Entry Level
Display Solutions
The PXD10 family represents a new generation of 32-bit
microcontrollers based on the Power Architecture®.
These devices provide a cost-effective, single chip
display solution for the industrial market. An integrated
TFT driver with digital video input ability from an
external video source, significant on-chip memory, and
low power design methodologies provide flexibility and
reliability in meeting display demands in rugged
environments. The advanced processor core offers high
performance processing optimized for low power
consumption, operating at speeds as high as 64 MHz.
The family itself is fully scalable from 512 KB to 1 MB
internal flash memory. The memory capacity can be
further expanded via the on-chip QuadSPI serial flash
controller module. Larger memory versions with greater
graphics functionality are planned for the future.
The PXD10 family platform has a single level of
memory hierarchy supporting on-chip SRAM and flash
memories. The 1 MB flash version features 160 KB of
on-chip graphics SRAM to buffer cost effective color

Module features
Low-power operation
PXD10 devices are designed for optimized low-power operation and dynamic power management of the
core processor and peripherals. Power management features include software-controlled clock gating of
peripherals and multiple power domains to minimize leakage in low-power modes.
There are two static low-power modes, STANDBY and STOP, and two dynamic power modes—RUN and
HALT. Both low power modes use clock gating to halt the clock for all or part of the device. The
STANDBY mode also uses power gating to automatically turn off the power supply to parts of the device
to minimize leakage.
STANDBY mode turns off the power to the majority of the chip to offer the lowest power consumption
mode. The contents of the cores, on-chip peripheral registers and potentially some of the volatile memory
are lost. STANDBY mode is configurable to make certain features available with the disadvantage that
these consume additional current:
• It is possible to retain the contents of the full RAM or only 8 KB.
• It is possible to enable the internal 16 MHz or 128 kHz RC oscillator, the external 4–16 MHz
oscillator, or the external 32 KHz oscillator.
• It is possible to keep the LCD module active.
The device can be awakened from STANDBY mode via from any of up to 19 I/O pins, a reset or from a
periodic wake-up using a low power oscillator.
STOP mode maintains power to the entire device allowing the retention of all on-chip registers and
memory, and providing a faster recovery low power mode than the lowest STANDBY mode. There is no
need to reconfigure the device before executing code. The clocks to the core and peripherals are halted and
can be optionally stopped to the oscillator or PLL at the expense of a slower start-up time.
STOP is entered from RUN mode only. Wake-up from STOP mode is triggered by an external event or by
the internal periodic wake-up, if enabled.
RUN modes are the main operating mode where the entire device can be powered and clocked and from
which most processing activity is done. Four dynamic RUN modes are supported—RUN0 - RUN3. The
ability to configure and select different RUN modes enables different clocks and power configurations to
be supported with respect to each other and to allow switching between different operating conditions. The

Features
necessary peripherals, clock sources, clock speed and system clock prescalers can be independently
configured for each of the four RUN modes of the device.
HALT mode is a reduced activity, low power mode intended for moderate periods of lower processing
activity. In this mode the core system clocks are stopped but user-selected peripheral tasks can continue to
run. It can be configured to provide more efficient power management features (switch-off PLL, flash
memory, main regulator, etc.) at the cost of longer wake up latency. The system returns to RUN mode as
soon as an event or interrupt is pending.

durations at wake up. Other delays will be necessary to consider including, but not limited to the external supply start-up time.
IRC Wake-up time must not be added to the overall wake-up time as it starts in parallel with the VREG.
All other wake-up times must be added to determine the total start-up time

Additional notes on low power operation:
• Fast wake-up using the on-chip 16 MHz internal RC oscillator allows rapid execution from RAM
on exit from low power modes
• The 16 MHz internal RC oscillator supports low speed code execution and clocking of peripherals
when it is selected as the system clock and can also be used as the PLL input clock source to
provide fast start-up without the external oscillator delay
• PXD10 devices include an internal voltage regulator that includes the following features:
— Regulates input to generate all internal supplies
— Manages power gating
— Low power regulators support operation when in STOP and STANDBY modes to minimize
power consumption
— Startup on-chip regulators in <50 µs for rapid exit of STOP and STANDBY modes
— Low voltage detection on main supply and 1.2 V regulated supplies
2.4.2
e200z0h core processor
The e200z0h processor is similar to other processors in the e200zx series but supports only the VLE
instruction set and does not include the signal processing extension for DSP applications or a floating point
unit.
The e200z0h has all the features of the e200z0 plus:
•
•
Branch acceleration using Branch Target Buffer (BTB)
Supports independent instruction and data accesses to different memory subsystems, such as
SRAM and Flash memory via independent Instruction and Data BIUs
The e200z0h processor uses a four stage in-order pipeline for instruction execution. The Instruction Fetch
(stage 1), Instruction Decode/Register file Read/Effective Address Calculation (stage 2), Execute/Memory
Access (stage 3), and Register Writeback (stage 4) stages operate in an overlapped fashion, allowing single
clock instruction execution for most instructions.
The integer execution unit consists of a 32-bit Arithmetic Unit (AU), a Logic Unit (LU), a 32-bit Barrel
shifter (Shifter), a Mask-Insertion Unit (MIU), a Condition Register manipulation Unit (CRU), a
Count-Leading-Zeros unit (CLZ), an 8 × 32 Hardware Multiplier array, result feed-forward hardware, and
a hardware divider.
Most arithmetic and logical operations are executed in a single cycle with the exception of the divide and
multiply instructions. A Count-Leading-Zeros unit operates in a single clock cycle. The Instruction Unit
contains a PC incrementer and a dedicated Branch Address adder to minimize delays during change of
flow operations. Branch target prefetching from the BTB is performed to accelerate certain taken branches.
Sequential prefetching is performed to ensure a supply of instructions into the execution pipeline. Branch
target prefetching is performed to accelerate taken branches. Prefetched instructions are placed into an
instruction buffer capable of holding four instructions.

Freescale Semiconductor
Features
Conditional branches not taken execute in a single clock. Branches with successful target prefetching have
an effective execution time of one clock on e200z0h. All other taken branches have an execution time of
two clocks.
Memory load and store operations are provided for byte, halfword, and word (32-bit) data with automatic
zero or sign extension of byte and halfword load data as well as optional byte reversal of data. These
instructions can be pipelined to allow effective single cycle throughput. Load and store multiple word
instructions allow low overhead context save and restore operations. The load/store unit contains a
dedicated effective address adder to allow effective address generation to be optimized. Also, a load-to-use
dependency does not incur any pipeline bubbles for most cases.
The Condition Register unit supports the condition register (CR) and condition register operations defined
by the Power Architecture. The condition register consists of eight 4-bit fields that reflect the results of
certain operations, such as move, integer and floating-point compare, arithmetic, and logical instructions,
and provide a mechanism for testing and branching.
Vectored and autovectored interrupts are supported. Hardware vectored interrupt support is provided to
allow multiple interrupt sources to have unique interrupt handlers invoked with no software overhead.
The CPU includes support for Variable Length Encoding (VLE) instruction enhancements. This allows the
classic PowerPC instruction set to be represented by a modified instruction set made up from a mixture of
16-bit and 32-bit instructions. This results in a significantly smaller code size footprint without affecting
performance noticeably.
The CPU core is enhanced by an additional interrupt source—Non Maskable Interrupt. This interrupt
source is routed directly from package pins, via edge detection logic in the SIU to the CPU, bypassing the
Interrupt Controller completely. Once the edge detection logic is programmed, it can not be disabled,
except by reset. The Non Maskable Interrupt is, as the name suggests, completely un-maskable and when
asserted will always result in the immediate execution of the respective interrupt service routine. The Non
maskable interrupt is not guaranteed to be recoverable.
The CPU core has an additional ‘Wait for Interrupt’ instruction that is used in conjunction with low power
STOP mode. When Low Power Stop mode is selected, this instruction is executed to allow the system
clock to be stopped. An external interrupt source or the system wake-up timer is used to restart the system
clock and allow the CPU to service the interrupt.
Additional features include:
• Load/store unit
— 1-cycle load latency
— Misaligned access support
— No load-to-use pipeline bubbles
• Thirty-two 32-bit general purpose registers (GPRs)
• Separate instruction bus and load/store bus Harvard architecture
• Reservation instructions for implementing read-modify-write constructs
• Multi-cycle divide (divw) and load multiple (lmw) store multiple (smw) multiple class
instructions, can be interrupted to prevent increases in interrupt latency
• Extensive system development support through Nexus debug port

2.4.3
Display Control Unit (DCU)
The DCU is a display controller designed to drive TFT LCD displays capable of driving up to WQVGA
resolution screens with 16 layers and 4 planes with real time alpha-blending.
The DCU generates all the necessary signals required to drive the display: up to 24-bit RGB data bus, Pixel
Clock, Data Enable, Horizontal-Sync and Vertical-Sync.
Internal memory resource of the PXD10 allows to easily handle complex graphics contents (pictures,
icons, languages, fonts) on a color TFT panel in up to Wide Quarter Video Graphics Array (WQVGA)
sizes. All the data fetches from internal and/or external memory are performed by the internal four-channel
DMA of the DCU providing a high speed/low latency access to the system backbone.
Control Descriptors (CDs) associated with each layer enable effective merging of different resolutions into
one plane to optimize use of internal memory buffers. A layer may be constructed from graphic content of
various resolutions including 1bpp, 2bpp, 4bpp, 8bpp, 16bpp, 24bpp and 24bpp+alpha. The ability of the
DCU to handle input data in resolutions as low as 1bpp, 2bpp and 4bpp enables a highly efficient use of
internal memory resources of the PXD10. A special tiled mode can be enabled on any of the 16 layers to
repeat a pattern optimizing graphic memory usage.
A hardware cursor can be managed independently of the layers at blending level increasing the efficient
use of the internal DCU resources.
To secure the content of all critical information to be displayed, a safety mode can be activated to check
the integrity of critical data along the whole system data path from the memory to the TFT pads.
The DCU features the following:
• Display color depth: up to 24 bpp
• Generation of all RGB and control signals for TFT
• Four-plane blending
• Maximum number of Input Layers: 16 (fixed priority)
• Dynamic look-up table (color and gamma look-up)
• blending range: up to 256 levels
• Transparency Mode
• Gamma Correction
• Tiled mode on all the layers
• Hardware cursor
• Critical display content integrity monitoring for functional safety support
• Internal Direct Memory Access (DMA) module to transfer data from internal and/or external
memory.

2.4.23
Interrupt Controller (INTC)
The INTC provides priority-based preemptive scheduling of interrupt requests, suitable for statically
scheduled hard real-time systems.
For high priority interrupt requests, the time from the assertion of the interrupt request from the peripheral
to when the processor is executing the interrupt service routine (ISR) has been minimized. The INTC
provides a unique vector for each interrupt request source for quick determination of which ISR needs to
be executed. It also provides an ample number of priorities so that lower priority ISRs do not delay the
execution of higher priority ISRs. To allow the appropriate priorities for each source of interrupt request,
the priority of each interrupt request is software configurable.
When multiple tasks share a resource, coherent accesses to that resource need to be supported. The INTC
supports the priority ceiling protocol for coherent accesses. By providing a modifiable priority mask, the
priority can be raised temporarily so that all tasks which share the resource can not preempt each other.
Multiple processors can assert interrupt requests to each other through software settable interrupt requests.
These same software settable interrupt requests also can be used to break the work involved in servicing
an interrupt request into a high priority portion and a low priority portion. The high priority portion is
initiated by a peripheral interrupt request, but then the ISR asserts a software settable interrupt request to
finish the servicing in a lower priority ISR. Therefore these software settable interrupt requests can be used
instead of the peripheral ISR scheduling a task through the RTOS. The INTC provides the following
features:

Crossbar Switch (XBAR)
The XBAR multi-port crossbar switch supports simultaneous connections between four master ports and
four slave ports. The crossbar supports a 32-bit address bus width and a 32-bit data bus width.
The crossbar allows four concurrent transactions to occur from any master port to any slave port but one
of those transfers must be an instruction fetch from internal flash. If a slave port is simultaneously
requested by more than one master port, arbitration logic selects the higher priority master and grants it
ownership of the slave port. All other masters requesting that slave port are stalled until the higher priority
master completes its transactions. Requesting masters having equal priority are granted access to a slave
port in round-robin fashion, based upon the ID of the last master to be granted access.
The crossbar provides the following features:
• 4 master ports
— e200z0h core instruction port
— e200z0h core complex load/store data port
— eDMA controller
