Product Summary
The Philips P80C550EFAA is a high-performance microcontroller fabricated with Philips high-density CMOS technology. This Philips CMOS technology combines the high speed and density characteristics of HMOS with the low power attributes of CMOS. Philips epitaxial substrate minimizes latch-up sensitivity. The P80C550EFAA contains a 4k × 8 EPROM (87C550)/ROM (83C550)/ROMless (80C550 has no program memory on-chip), a 128 × 8 RAM, 8 channels of 8-bit A/D, four 8-bit ports (port 1 is input only), a watchdog timer, two 16-bit counter/timers, a seven-source, two-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and an on-chip oscillator and clock circuits.
Parametrics
P80C550EFAA absolute maxing ratings: (1)Operating temperature under bias: –40 to +85℃; (2)Storage temperature range: –65 to +150℃; (3)Voltage on EA/VPP pin to VSS (87C550 only): 0 to +13.0 V; (4)Voltage on any other pin to VSS: –0.5 to +6.5 V; (5)Input, output current on any two I/O pins: ±10 mA; (6)Power dissipation (based on package heat transfer limitations, not device power consumption): 1.5 W.
