It integrates a PLL-based clock generator, 16-channel 12-bit ADC, CAN 2.0B controller, and 80-pin LQFP package. It targets automotive body electronics and industrial control systems requiring functional safety support and deterministic real-time response.
For engineers reviewing the UPD70F3375M2GCA-UEU-AX datasheet, UPD70F3375M2GCA-UEU-AX pinout, UPD70F3375M2GCA-UEU-AX application, or UPD70F3375M2GCA-UEU-AX equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral integration (CAN, ADC, PLL), and direct alternative part comparisons for automotive-grade MCU selection.
Technical Context
The UPD70F3375M2GCA-UEU-AX implements the V850ES CPU core with 32-bit RISC architecture, supporting Thumb-compatible instruction set extensions and hardware multiply/divide. Its clock system includes a programmable PLL with 1–40 MHz input range and selectable output dividers to generate stable system clocks up to 40 MHz.
Interrupt handling uses a priority-based INTC with 128 vectors, non-maskable interrupt (NMI) support, and configurable maskable interrupt sources including timer overflows, ADC completion, CAN message reception, and external edge-triggered inputs - all synchronized to the internal bus clock domain.
