Product details
Overview
M3062LFGPFP#U3C from Renesas Electronics is a 16-bit Flash-based microcontroller in the M16C/62P Group, built on the M16C/60 Series CPU core. It features 256 KB + 4 KB Flash ROM, 20 KB RAM, operates at up to 24 MHz (41.7 ns min instruction time), and supports single-chip mode with 1 MB address space - designed for real-time control in industrial motor drives and embedded OA equipment.
For engineers reviewing the M3062LFGPFP#U3C datasheet, M3062LFGPFP#U3C pinout, M3062LFGPFP#U3C application, or M3062LFGPFP#U3C equivalent, this part delivers deterministic interrupt response (7 priority levels), integrated 10-bit 26-channel ADC, dual 8-bit DACs, and IEBus/I²C serial interfaces - critical for timing-sensitive motion control and sensor fusion systems.
Technical Context
The M3062LFGPFP#U3C implements a silicon-gate CMOS M16C/60 core with 91 basic instructions and hardware multiplier, enabling high-efficiency arithmetic for servo loop computation. Its clock system includes main/sub oscillators, on-chip oscillator, and PLL synthesizer - all with oscillation stop detection and re-oscillation recovery.
Peripheral integration includes two 2-channel DMACs, CCITT-CRC circuit, watchdog timer (15-bit with prescaler), and multifunction timers (Timer A: 5×16-bit channels; Timer B: 6×16-bit channels) with three-phase motor control capability - supporting precise PWM generation and encoder input capture without external logic.
