80C554 - 80C51 8-bit microcontroller

Description

This data sheet describes the 6 clock version of the 8xC554.

This device is only available in 64L LQFP.

The 8xC554 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family.

Features

• 83C554.
• 16k bytes ROM.
• 80C554.
• ROMless version.
• 87C554.
• 16k bytes EPROM The 87C554 contains a 16k × 8 non-volatile EPROM, a 512 × 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, four-priority-level, nested interrupt structure, an 7-input ADC, a dual DAC pulse width modulated.
