Product Summary
The P80C552IBA is a Single-Chip 8-Bit Microcontroller. The P80C552IBA is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The P80C552IBA contains a non-volatile 8k × 8 read-only program memory, a volatile 256 × 8 read/write data memory, five 8-bit I/O ports, one 8-bit input port, two 16-bit timer/event counters (identical to the timers of the 80C51), an additional 16-bit timer coupled to capture and compare latches, a 15-source, two-priority-level, nested interrupt structure, an 8-input ADC, a dual DAC pulse width modulated interface, two serial interfaces (UART and I2C-bus), a watchdog timer and on-chip oscillator and timing circuits. For systems that require extra capability, the P80C552IBA can be expanded using standard TTL compatible memories and logic.
Parametrics
P80C552IBA absolute maximum ratings: (1)Storage temperature range: –65 to +150 ℃; (2)Voltage on any other pin to VSS: –0.5 to +6.5 V; (3)Input, output DC current on any single I/O pin: 5.0 mA; (4)Power dissipation: 1.0 W.
