83C552
83C552 is Single-chip 8-bit microcontroller manufactured by NXP Semiconductors.
DESCRIPTION
The 80C552/83C552 (hereafter generically referred to as 8XC552) Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 8XC552 has the same instruction set as the 80C51. Three versions of the derivative exist:
- 83C552- 8 kbytes mask programmable ROM
- 80C552- ROMless version of the 83C552
- 87C552- 8 kbytes EPROM (described in a separate chapter)
The 8XC552 contains a non-volatile 8k × 8 read-only program memory (83C552), a volatile 256 × 8 read/write data memory, five 8-bit I/O ports, one 8-bit input port, two 16-bit...
