PRODUCT OVERVIEW
PRODUCT OVERVIEW
OVERVIEW
The S3C72F5 single-chip CMOS microcontroller has been designed for high performance using Samsung's
newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).
With an up-to-896-dot LCD direct drive capability, 8-bit and 16-bit timer/counter, and serial I/O, the S3C72F5
offers an excellent design solution for a wide variety of applications which require LCD functions.
Up to 39 pins of the 100-pin QFP package can be dedicated to I/O. Eight vectored interrupts provide fast
response to internal and external events. In addition, the S3C72F5's advanced CMOS technology provides for
low power consumption and a wide operating voltage range.
OTP
The S3C72F5 microcontroller is also available in OTP (One Time Programmable) version, S3P72F5. S3P72F5
microcontroller has an on-chip 16K-byte one-time-programable EPROM instead of masked ROM. The S3P72F5
is comparable to S3C72F5, both in function and in pin configuration.

S3P72F5 OTP
S3P72F5 OTP
OVERVIEW
The S3P72F5 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the S3C72F5
microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data
format.
The S3P72F5 is fully compatible with the S3C72F5, both in function and in pin configuration. Because of its
simple programming requirements, the S3P72F5 is ideal for use as an evaluation chip for the S3C72F5.

OPERATING MODE CHARACTERISTICS
When 12.5 V is supplied to the VPP(TEST) pin of the S3P72F5, the EPROM programming mode is entered. The
operating mode (read, write, or read protection) is selected according to the input signals to the pins listed in
Table 16–3 below.

NOTES:
1. Data includes power consumption for subsystem clock oscillation.
2. When the system clock control register, SCMOD, is set to 1001B, main system clock oscillation stops and the
subsystem clock is used.
3. Currents in the following circuits are not included; on-chip pull-up resistors, internal LCD voltage dividing resistors,
output port drive currents.
