80c51 8-bit Microcontroller . 6 Clock Operation 16k/512 Otp/rom/romless, 7 Channel 10 Bit A/d, I2c, Pwm, Capture/compare, High I/o, 64l Lqfp - Nxp Semiconductors

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. The 87C554 has the same instruction set as the 80C51. Three versions of the derivative exist: 83C55416k bytes ROM 80C554ROMless version 87C55416k 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 Interface two serial Interfaces (UART and I 2C-bus), a watchdog Timer and on-chip Oscillator and Timing circuits. For systems that require extra capability, the 8xC554 CAN be expanded using standard TTL compatible Memories and Logic In addition, the 8xC554 has two software selectable modes of power reductionidle mode and power-down mode. The idle mode freezes the CPU while allowing the RAM, Timers serial ports, and interrupt system to continue functioning. Optionally, the ADC CAN be operated in Idle mode. The power-down mode saves the RAM contents but freezes the Oscillator causing all other chip functions to be inoperative. By NXP Semiconductors
