Product Summary

The MC68HC11A1FN is an 8-bit microcontroller. The high speed, low power consumption chip has multiplexed buses and a fully static design. The MC68HC11A1FN can operate at frequencies from 3 MHz to DC. The three MCUs are created from the same masks; the only difference is the value stored in the CONFIG register, and whether or not the ROM or EEPROM is tested and guaranteed.

Parametrics

MC68HC11A1FN absolute maximum ratings: (1)Average Junction Temperature, TJ|: TA + (PD x QJA)℃; (2)Ambient Temperature, TA: User-determined ℃ ; (3)Package Thermal Resistance (Junction-to-Ambient) 52-Pin Plastic Quad Pack (PLCC), θJA: 50℃/W; 48-Pin Plastic Dual In-Line Package (DIP), θJA: 40℃/W; (4)Total Power Dissipation, PD: PINT + PI/O K /(TJ + 273℃)W; (5)Device Internal Power Dissipation, PINT: IDD x VDD W; (6)I/O Pin Power Dissipation, PI/O: User-determined W; (7)A Constant, K: PD x (TA + 273℃) +θJA x PD2 W·℃; (8)Output Low Voltage, ILoad = 1.6 mA, VOL: 0.4V.
