AM8048
AM8048 is Single Chip a-Bit Microcomputers manufactured by AMD.
DESCRIPTION x The Am8048 contains a 1k 8 program memory, a 64 x 8
RAM data memory, 27 I/O lines, and an 8-bit timer/counter in addition to on board oscillator and clock circuits. For systems that require extra capability, the Am8048 can be expanded using. standard memories and Am9080A peripherals. The Am8035 is the equivalent of an Am8048 without program memory.
The microprocessor is designed to be an efficient controller. The Am8048' has extensive bit handling capability 'as 'well as facilities for both binary and BCD arithmetic. Efficient use of program memory results from an instruction set consisting' mostly of single byte instructions and no instructions over two bytes in length.
