Product details
Overview
M30263F6AFP#U5A from Renesas Electronics is a 16-bit single-chip microcontroller in the M16C/26A Group, designed for embedded control in industrial and consumer systems. It integrates 256 KB on-chip flash memory, 16 KB RAM, a 16-bit CPU core, 5-channel 16-bit timer/counters, and supports up to 48 MHz operation with a 3.3 V supply. It is used in motor control subsystems requiring real-time I/O handling and deterministic interrupt response.
For engineers reviewing the M30263F6AFP#U5A datasheet, M30263F6AFP#U5A pinout, M30263F6AFP#U5A application, or M30263F6AFP#U5A equivalent, key selection criteria include its 100-pin LQFP package, integrated watchdog timer with window function, voltage detection circuit (2.7 V threshold), dual clock sources (main/sub), and support for both Wait and Stop low-power modes - all critical for resource-constrained, safety-aware control designs.
Technical Context
The M30263F6AFP#U5A implements the M16C CPU architecture with 16-bit data bus width and 24-bit address space, enabling direct access to its full 256 KB flash and 16 KB RAM without banking. Its peripheral set includes three UART channels (one with IrDA support), a 10-bit 16-channel ADC, and a programmable 16-bit PWM generator with dead-time insertion - all synchronized to the same system clock domain.
It features dual reset sources: hardware reset via dedicated RESB pin and software-initiated reset through the RSTCR register. The clock generation circuit supports main crystal (1–20 MHz), sub-crystal (32.768 kHz), and on-chip oscillator (1 MHz) inputs, with PLL multiplication up to ×4 for CPU clock derivation - allowing flexible trade-offs between accuracy, startup time, and power consumption.
