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
