P83C528FFA/XXX Datasheet

CMOS single-chip 8-bit microcontroller


The 8XC528 single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 8XC528 has the same instruction set as the 80C51. Three versions of the derivative exist:

•83C528 — 32k bytes mask programmable ROM
•80C528 — ROMless version of the 83C528
•87C528 — 32k bytes EPROM (described in a separate data sheet)

•80C51 instruction set
–32k ×8 ROM (83C528)
–ROMless (80C528)
–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
–Four 8-bit I/O ports
•Power control modes:
–Idle mode
–Power-down mode
–Warm start from power-down
•CMOS and TTL compatible
•Extended temperature ranges
•ROM code protection
•7-source and 7-vector interrupt structure with 2 priority levels
•Up to 3 external interrupt request inputs
•Two programmable power reduction modes (Idle and Power-down)
•Termination of Idle mode by any interrupt, external or WDT (watchdog) reset
•XTAL frequency range: 1.2 MHz to 16 MHz
