Product Summary

The MC68HC11F1CPU4 is an 8-Bit Microcontroller. High-speed expanded systems required the development of the MC68HC11F1CPU4 with its extra input/output (I/O) ports, an increase in static RAM (one Kbyte), internal chip-select functions, and a non-multiplexed bus which reduces the need for external interface logic. The timer, serial I/O, and analog-to-digital (A/D) converter enable functions similar to those found in the MC68HC11E9.

Parametrics

MC68HC11F1CPU4 absolute maximum ratings: (1)Supply Voltage:-0.3 to + 7.0 V; (2)Input Voltage:-0.3 to + 7.0 V; (3)Operating Temperature Range:-40 to + 85℃; (4)Storage Temperature Range:-55 to + 150℃; (5)Current Drain per Pin Excluding VDD, VSS, AVDD, VRH, and VRL:25 mA.
