87C528
FEATURES - 80C51 instruction set - 512 × 8 RAM - Memory addressing capability 64k ROM and 64k RAM - Three 16-bit counter/timers - On-chip watchdog timer with oscillator - Full duplex UART - I2C serial interface DESCRIPTION The 87C528 single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 87C528 has the same instruction set as the 80C51. Three versions of the derivative exist: - Power control modes: - Idle mode - Power-down mode - Warm start from power-down - 83C528- 32k bytes ROM - 83C524- 16k bytes ROM - 80C528- ROMless version of the 83C528 - 87C528- 32k bytes EPROM - 83C524- 16k bytes EPROM - CMOS and TTL patible - Extended temperature ranges - EPROM code protection - OTP package available - 16 MHz speed at VCC = 5 V This device provides architectural enhancements that make it applicable in a variety of applications in consumer, tele and general control systems, especially in those systems which...
