Product Summary
The P80C31SBAA is an 8-bit microcontroller design fabricated with Philips high-density CMOS technology with operation from 2.7V to 5.5V. The P80C31SBAA contains a 4k × 8 ROM, a 128 × 8 RAM, 32 I/O lines, three 16-bit counter/timers, a six-source, four-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and on-chip oscillator and clock circuits. In addition, the device is a low power static design which offers a wide range of operating frequencies down to zero. Two software selectable modes of power reduction—idle mode and power-down mode are available.
Parametrics
P80C31SBAA absolute maximum ratings: (1)Operating temperature under bias: 0 to +70 or -40 to +85 ℃; (2)Storage temperature range: -65 to +150 ℃; (3)Voltage on EA/VPP pin to VSS: 0 to +13.0 V; (4)Voltage on any other pin to VSS: -0.5 to +6.5 V; (5)Maximum IOL per I/O pin: 15 mA; (6)Power dissipation (based on package heat transfer limitations, not device power consumption): 1.5 W.
Features
P80C31SBAA features: (1)CMOS and TTL compatible; (2)TWO speed ranges at VCC = 5V; (3)Three package styles; (4)Extended temperature ranges; (5)Dual Data Pointers; (6)Encryption array—64 bytes; (7)4 level priority interrupt; (8)6 interrupt sources; (9)Four 8-bit I/O ports; (10)Full–duplex enhanced UART; (11)Programmable clock out; (12)Asynchronous port reset; (13)Low EMI (inhibit ALE); (14)Wake-up from Power Down by an external interrupt (8XC51).
