Renesas | UPD78F0495GK-GAK-AX

UPD78F0495GK-GAK-AX microcontroller features highly optimized, high-performance, 150 nm flash process technology that provides the microcontroller with low power operation at full speed (10 MHz) and very low power consumption in Standby/HALT modes (1 μA typical in STOP, 2.4 μA typical in HALT mode with 32 kHz/real-time clock running).

Dense flash memory provides 6 bits ECC on every 32-bit word to protect against any rare flash data retention failures in long-term field usage (15-20 years). LCD-resistive ladder drive allows up to 160 (x 4) or 288 (x 8) LCD segment display. High-performance CPU processing, generous GP I/O lines and peripheral functions enable the electronics hardware/software designer greater flexibility and ease-of-use.

Features:

• Low-power, 8-bit 78K0 flash MCU, 1.8 V to 5.5 V operation
