Product details
Overview
M30280FAWG#U5B from Renesas Electronics is a 16-bit single-chip microcontroller in the M16C/28 Group, designed for embedded control in industrial and consumer systems. It integrates 256 KB flash memory, 16 KB RAM, a 16-bit CPU core, on-chip PLL clock generator, and peripheral functions including UART, I2C-compatible serial interface, 10-bit ADC, and 16-bit timer arrays. It operates at up to 20 MHz with supply voltage of 2.7–5.5 V.
For engineers reviewing the M30280FAWG#U5B datasheet, M30280FAWG#U5B pinout, M30280FAWG#U5B application, or M30280FAWG#U5B equivalent, key selection considerations include its 100-pin LQFP package, integrated low-voltage detection circuit, hardware watchdog timer, stop/wait power modes, and compatibility with Renesas' M16C/Tiny development tools and C compiler suite.
Technical Context
The M30280FAWG#U5B implements the M16C CPU architecture with 16-bit data bus and 24-bit address space, supporting both big-endian and little-endian data access via software configuration. Its clock system includes main clock (up to 20 MHz), sub-clock (32.768 kHz), on-chip oscillator, and PLL multiplier enabling flexible system timing without external crystal for many applications.
Peripheral integration includes three 16-bit timer units (TMR0–TMR2) with capture/compare and PWM output capability, a 10-channel 10-bit ADC with internal reference, and dual serial interfaces - one UART and one I2C-compatible channel - all mapped to dedicated SFRs with interrupt vector support and configurable baud rates.

Pinout & Package
The M30280FAWG#U5B is housed in a 100-pin LQFP package with exposed thermal pad (EP), optimized for thermal dissipation in industrial control applications. Pin assignments follow Renesas' standardized M16C/28 Group layout, with dedicated power/ground pairs, configurable I/O ports (P0–P15), and function-mapped peripheral pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pairs per quadrant reduce noise coupling; EP connects to GND for thermal stability |
| P00–P07 | Port 0 I/O | Bi-directional CMOS port with pull-up enable; default reset state is high-impedance input |
| P10–P17 | Port 1 I/O | Shared with UART0 TX/RX, TMR0/1 inputs, and ADC trigger - multiplexing controlled by PM registers |
| CLKP, CLKN | Differential main clock input | Accepts external crystal (1–20 MHz) or LVDS clock source; enables precise PLL lock |
| RESET | Active-low reset input | Asynchronous edge-triggered; internal pull-up ensures valid reset on power-up |
| AD0–AD9 | ADC analog inputs | Support simultaneous sampling across 10 channels; internal sample-and-hold enabled per channel |
Key Features
| Feature | Design Value |
|---|---|
| On-chip PLL clock generator | Enables stable 20 MHz operation from low-frequency crystals (e.g., 4–5 MHz), reducing EMI and BOM cost |
| Low-voltage detection (LVD) | Configurable trip points (2.5 V, 2.7 V, 3.0 V, 3.5 V, 4.0 V) with interrupt or reset output - prevents erratic operation during brownout |
| Hardware watchdog timer (WDT) | Independent 14-bit counter with windowed refresh mode - detects firmware hang without CPU intervention |
| Stop/Wait power modes | Stop mode draws ≤1.5 µA (VDD = 3.3 V); Wait mode retains RAM and SFRs while halting CPU - extends battery life in portable devices |
| I²C-compatible serial interface | Supports standard (100 kbps) and fast-mode (400 kbps) speeds; slave address programmable via SFR - simplifies sensor/EEPROM interfacing |
