DESCRIPTION

The 87C552 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 87C552 has the same instruction set as the 80C51. Three versions of the derivative exist:

• 83C552—8k bytes mask programmable ROM

• 80C552—ROMless version of the 83C552

• 87C552—8k bytes EPROM

FEATURES

• 80C51 central processing unit

• 8k × 8 EPROM expandable externally to 64k bytes

• An additional 16-bit timer/counter coupled to four capture registers and three compare registers

• Two standard 16-bit timer/counters

• 256 × 8 RAM, expandable externally to 64k bytes

• Capable of producing eight synchronized, timed outputs

• A 10-bit ADC with eight multiplexed analog inputs

• Two 8-bit resolution, pulse width modulation outputs

• Five 8-bit I/O ports plus one 8-bit input port shared with analog inputs

• I2C-bus serial I/O port with byte oriented master and slave functions

• Full-duplex UART compatible with the standard 80C51

• On-chip watchdog timer

• 16MHz speed

• Extended temperature ranges

• OTP package available
