TLC156
GENERAL DESCRIPTION
The TLC156 series is a family of low-cost, high speed, high noise immunity, EPROM/ROM-based 8-bit CMOS
microcontrollers. It employs a RISC architecture with only 42 instructions. All instructions are single cycle except
for program branches which take two cycles. The easy to use and easy to remember instruction set reduces
development time significantly.
The TLC156 series consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer (PWRT),
Oscillator Start-up Timer(OST), Watchdog Timer, EPROM/ROM, SRAM, tri-state I/O port, I/O
pull-high/open-drain/pull-down control, Power saving SLEEP mode, real time programmable clock/counter,
Interrupt, Wake-up from SLEEP mode, and Code Protection for EPROM products. There are four oscillator
configurations to choose from, including the power-saving LP (Low Power) oscillator and cost saving RC oscillator.
The TLC154 and TLC155 address 512Ã13 of program memory, the TLC156 address 1KÃ13 of
program memory, and the TLC157 address 2KÃ13 of program memory.
The TLC156 can directly or indirectly address its register files and data memory. All special function registers
including the program counter are mapped in the data memory.
