Product details
Overview
M30280F8HP#U7B from Renesas Electronics is a 16-bit single-chip microcontroller in the M16C/28 Group, featuring 128 KB on-chip flash memory, 8 KB RAM, and integrated peripherals including UART, I2C-compatible serial interface, 16-bit timer/counters, and 10-bit ADC. It operates at up to 20 MHz CPU clock frequency with 3.0–5.5 V supply voltage and targets industrial control and embedded instrumentation applications.
For engineers reviewing the M30280F8HP#U7B datasheet, M30280F8HP#U7B pinout, M30280F8HP#U7B application, or M30280F8HP#U7B equivalent, key selection criteria include its 100-pin LQFP package, 10-bit ADC resolution with 16 input channels, hardware multiplier support, low-power STOP/WAIT modes, and compatibility with Renesas' M16C development tools and C compiler suite.
Technical Context
The M30280F8HP#U7B implements the M16C CPU core with 16-bit data bus and 24-bit address space, supporting both 16-bit and 32-bit arithmetic via dedicated hardware multiplier/divider. Its clock system integrates main crystal oscillator (1–20 MHz), sub-oscillator (32.768 kHz), on-chip RC oscillator, and PLL for flexible clock generation across operating modes.
Peripheral integration includes three 16-bit timer/counters with PWM output capability, two asynchronous serial interfaces (UART mode), one synchronous serial interface (I2C-compatible), and a 10-bit successive-approximation ADC with sample-and-hold and automatic channel scanning - all directly memory-mapped and controllable via SFRs without external glue logic.
