FUNCTION OVERVIEW
SAM47 CPU
All S3C7-series microcontrollers have the advanced SAM47 CPU core. The SAM47 CPU can directly address up
to 32 K bytes of program memory. The arithmetic logic unit (ALU) performs 4-bit addition, subtraction, logical,
and shift-and-rotate operations in one instruction cycle and most 8-bit arithmetic and logical operations in two
cycles.
CPU REGISTERS
Program Counter
A 14-bit program counter (PC) stores addresses for instruction fetches during program execution. Usually, the PC
is incremented by the number of bytes of the fetched instruction. The one instruction fetch that does not
increment the PC is the 1-byte REF instruction which references instructions stored in a look-up table in the
ROM. Whenever a reset operation or an interrupt occurs, bits PC13 through PC0 are set to the vector address.
Stack Pointer
An 8-bit stack pointer (SP) stores addresses for stack operations. The stack area is located in general-purpose
data memory bank 0. The SP is 8-bit read/writeable and SP bit 0 must always be logic zero.
During an interrupt or a subroutine call, the PC value and the PSW are written to the stack area. When the
service routine has completed, the values referenced by the stack pointer are restored. Then, the next instruction
is executed.
The stack pointer can access the stack despite data memory access enable flag status. Since the reset value of
the stack pointer is not defined in firmware, you use program code to initialize the stack pointer to 00H. This sets
the first register of the stack area to data memory location 0FFH.
PROGRAM MEMORY
In its standard configuration, the 16,384 × 8-bit ROM is divided into four areas:
— 16-byte area for vector addresses
— 16-byte general-purpose area (0010–001FH)
— 96-byte instruction reference area
— 16,256-byte area for general-purpose program memory
The vector address area is used mostly during reset operations and interrupts. These 16 bytes can alternately be
used as general-purpose ROM.
The REF instruction references 2 x 1-byte or 2-byte instructions stored in reference area locations 0020H–
007FH. REF can also reference three-byte instructions such as JP or CALL. So that a REF instruction can
reference these instructions, however, the JP or CALL must be shortened to a 2-byte format. To do this, JP or
CALL is written to the reference area with the format TJP or TCALL instead of the normal instruction name.
Unused locations in the REF instruction look-up area can be allocated to general-purpose use.

PRODUCT OVERVIEW
DATA MEMORY
Overview
The 512 × 4 bit data memory has four areas:
— 32 × 4-bit working register area
— 224 × 4-bit general-purpose area in bank 0 which is also used as the stack area
— 256 × 4-bit general-purpose area in bank 1
— 128 × 4-bit area in bank 15 for memory-mapped I/O addresses
The data memory area is also organized as three memory banks — bank 0, bank 1, and bank 15. You use the
select memory bank instruction (SMB) to select one of the banks as working data memory.
Data stored in RAM locations are 1-, 4-, and 8-bit addressable. After a hardware reset, data memory initialization
values must be defined by program code.
Data Memory Addressing Modes
The enable memory bank (EMB) flag controls the addressing mode for data memory banks 0, 1, or 15. When the
EMB flag is logic zero, only locations 00H–7FH of bank 0 and bank 15 can be accessed. When the EMB flag is
set to logic one, all three data memory banks can be accessed based on the current SMB value.
Working Registers
The RAM's working register area in data memory bank 0 is also divided into four register banks. Each register
bank has eight 4-bit registers. Paired 4-bit registers are 8-bit addressable.
Register A can be used as a 4-bit accumulator and double register EA as an 8-bit extended accumulator; double
registers WX, WL, and HL are used as address pointers for indirect addressing.
To limit the possibility of data corruption due to incorrect register addressing, it is advisable to use bank 0 for
main programs and banks 1, 2, and 3 for interrupt service routines.
Bit Sequential Carrier
The bit sequential carrier (BSC) mapped in data memory bank 15 is a 8-bit general register that you can
manipulate using 1-, 4-, and 8-bit RAM control instructions.
Using the BSC register, addresses and bit locations can be specified sequentially using 1-bit indirect addressing
instructions. In this way, a program can generate 8-bit data output by moving the bit location sequentially,
incrementing or decrementing the value of the L register. You can also use direct addressing to manipulate data
in the BSC.

CONTROL REGISTERS
Program Status Word
The 8-bit program status word (PSW) controls ALU operations and instruction execution sequencing. It is also
used to restore a program's execution environment when an interrupt has been serviced. Program instructions
can always address the PSW regardless of the current value of data memory access enable flags.
Before an interrupt is processed, the PSW is pushed onto the stack in data memory bank 0. When the routine is
completed, PSW values are restored.

IS0
EMB
ERB
C
SC2
SC1
SC0
Interrupt status flags (IS1, IS0), the enable memory bank and enable register bank flags (EMB, ERB), and the
carry flag (C) are 1- and 4-bit read/write or 8-bit read-only addressable. Skip condition flags (SC0–SC2) can be
addressed using 8-bit read instructions only.
Select Bank (SB) Register
Two 4-bit locations called the SB register store address values used to access specific memory and register
banks: the select memory bank register, SMB, and the select register bank register, SRB.
'SMB n' instructions select a data memory bank (0, 1, or 15) and store the upper four bits of the 12-bit data
memory address in the SMB register. The 'SRB n' instruction is used to select register bank 0, 1, 2, or 3, and to
store the address data in the SRB.
The instructions 'PUSH SB' and 'POP SB' move SMB and SRB values to and from the stack for interrupts and
subroutines.
CLOCK CIRCUITS
Main system and subsystem oscillation circuits generate the internal clock signals for the CPU and peripheral
hardware. The main system clock can use a crystal, ceramic, or RC oscillation source, or an externally-generated
clock signal. The subsystem clock requires either a crystal oscillator or an external clock source.
Bit settings in the 4-bit power control and system clock mode registers select the oscillation source, the CPU
clock, and the clock used during power-down mode. The internal system clock signal (fxx) can be divided internally to produce three CPU clock frequencies — fxx/4, fxx/8, or fxx/64.
INTERRUPTS
Interrupt requests may be generated internally by on-chip processes (INTB, INTT0, INTT1, and INTS) or
externally by peripheral devices (INT0, INT1, and INT4). There are two quasi-interrupts: INT2 and INTW.
INT2/KS0–KS7 detects rising/falling edges of incoming signals and INTW detects time intervals of 0.5 seconds
or 3.91 milliseconds at the watch timer clock frequency of 32.768 kHz. The following components support
interrupt processing:
— Interrupt enable flags
— Interrupt request flags
— Interrupt priority registers
— Power-down termination circuit
1-6
S3C7515/P7515
PRODUCT OVERVIEW
POWER-DOWN
To reduce power consumption, there are two power-down modes: idle and stop. The IDLE instruction initiates idle
mode and the STOP instruction initiates stop mode.
In idle mode, only the CPU clock stops while peripherals and the oscillation source continue to operate normally.
Stop mode effects only the main system clock — a subsystem clock, if used, continues oscillating. In stop mode,
main system clock oscillation stops completely, halting all operations except for a few basic peripheral functions.
RESET or an interrupt (with the exceptions of INT0) can be used to terminate either idle or stop mode.
RESET
When a RESET signal occurs during normal operation or during power-down mode, the CPU enters idle mode
when the reset operation is initiated. When the standard oscillation stabilization interval (36.6 ms at 3.579545
MHz) has elapsed, normal CPU operation resumes.
I/O PORTS
The S3C7515/P7515 has 14 I/O ports. Pin addresses for all I/O ports are mapped in bank 15 of the RAM. There
are 4 input pins, 43 configurable I/O pins, and 8 n-channel open-drain I/O pins, for a total of 55 I/O pins. The
contents of I/O port pin latches can be read, written, or tested at the corresponding address using bit
manipulation instructions.
TIMERS and TIMER/COUNTERS
The timer function has four main components: an 8-bit basic interval timer, two 8-bit timer/counters, and a watch
timer. The 8-bit basic timer generates interrupt requests at precise intervals, based on the selected CPU clock
frequency.
The programmable 8-bit timer/counters are used for external event counting, generation of arbitrary clock
frequencies for output, and dividing external clock signals. The 8-bit timer/counter 0 generates a clock signal
(SCK) for the serial I/O interface.
The watch timer has an 8-bit watch timer mode register, a clock selector, and a frequency divider circuit. Its
functions include real-time and watch-time measurement, and frequency outputs for buzzer sound.
SERIAL I/O INTERFACE
The serial I/O interface supports the transmission or reception of 8-bit serial data with an external device. The
serial interface has the following functional components:
— 8-bit mode register
— Clock selector circuit
— 8-bit buffer register
— 3-bit serial clock counter
The serial I/O circuit can be set either to transmit-and-receive or to receive-only mode. MSB-first or LSB-first
transmission is also selectable. The serial interface operates with an internal or an external clock source, or using
the clock signal generated by the 8-bit timer/counter 0. To modify transmission frequency, the appropriate bits in
the serial I/O mode register (SMOD) must be manipulated.

S3P7515 OTP
S3P7515 OTP
OVERVIEW
The S3P7515 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the S3C7515
microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data
format.
The S3P7515 is fully compatible with the S3C7515, both in function and in pin configuration. Because of its
simple programming requirements, the S3P7515 is ideal for use as an evaluation chip for the S3C7515.
