SC73P1601
4-BIT MCU FOR REMOTE CONTROLLER(OTP TYPE)
DESCRIPTION
SC73P1601 is one of Silan’s 4-bit CMOS single-chip micro-
controllers for infrared remote control transmitters (IRCTs). It can be
implemented in various IRCTs circuits by OTP program. And it is
compatible with SC73C1602 on software and package.

FUNCTION DESCRIPTION
SC73P1601 includes 4-bit MCU, outlay oscillator, system reset module. Next we will mainly introduce the
functions.
1. PC
PC refers to the program address pointer, 10 bits. The maximum addressing space is 1K ROM .The program
counter contains the address of the instruction that will be executed next. The PC value is cleared to 0 after reset.
The PC is set to predefined value when one of the 3 following occasions occurs: 1) when the JUMP instruction is
executed; 2) when a subroutine call is back; 3) when a program call is back. In the SC73P1601, all instructions
are one-byte instructions, PC increments by 1 each time an instruction is executed.
