It operates at up to 20 MHz and targets industrial control and automotive body electronics.
For engineers reviewing the UPD78F1814AGAA2-GAM-G datasheet, UPD78F1814AGAA2-GAM-G pinout, UPD78F1814AGAA2-GAM-G application, or UPD78F1814AGAA2-GAM-G equivalent, key selection considerations include its 48-pin LQFP package, CAN interface support, Flash endurance (100,000 write/erase cycles), operating voltage range (2.7–5.5 V), and AEC-Q100 Grade 2 qualification for automotive use.
Technical Context
The UPD78F1814AGAA2-GAM-G implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a dedicated CAN controller supporting both standard and extended frames, with programmable bit timing and message object buffers.
Its peripheral suite includes three 16-bit timer arrays (each with capture/compare/PWM functions), a watchdog timer with independent clock source, and an on-chip voltage regulator for internal logic supply. The device supports in-circuit debugging via on-chip debug interface and flash self-programming capability.
