Product details
Overview
M30281F6HP#UFB 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 features 64 KB on-chip Flash memory, 4 KB RAM, a 16-bit CPU core, 52-pin LQFP package, and operates at up to 20 MHz with supply voltage of 2.7–5.5 V.
For engineers reviewing the M30281F6HP#UFB datasheet, M30281F6HP#UFB pinout, M30281F6HP#UFB application, or M30281F6HP#UFB equivalent, key selection criteria include Flash endurance (10,000 write/erase cycles), integrated watchdog timer, low-power stop/wait modes, and support for UART, I²C-compatible serial interface, and 10-bit ADC with 8 channels.
Technical Context
The M30281F6HP#UFB implements the M16C CPU architecture with 16-bit data bus and 24-bit address space, supporting both CISC instruction set and efficient bit manipulation. It integrates a programmable 8-bit/16-bit timer array (MTU), 10-bit successive-approximation ADC, and dual serial interfaces - one UART and one I²C-compatible serial interface (CSI) - all mapped to dedicated SFRs.
Its clock system includes main clock (1–20 MHz crystal), sub-clock (32.768 kHz), on-chip oscillator (1 MHz), and PLL for internal CPU clock multiplication. Reset sources include hardware reset, watchdog timer reset, oscillation stop detection, and low-voltage detection interrupt - all configurable via dedicated control registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21282SNFP#U0 | Same M16C/28B core, 64 KB Flash, but 64-pin LQFP; adds CAN controller and enhanced DMA | Required for CAN-based industrial networks; larger package increases PCB area and cost | Select when CAN bus integration is mandatory and board space allows 64-pin layout |
| RL78/G13 R5F100PLGSP#30 | 16-bit RL78 core, 64 KB Flash, 10-bit ADC, but lower max frequency (24 MHz), different peripheral register map | Higher code density and ultra-low power (0.57 µA stop mode), but requires full firmware porting | Choose for new designs prioritizing energy efficiency and long battery life over legacy code reuse |
Compared with M30281F6HP#UFB, R5F21282SNFP#U0 offers CAN capability at the cost of larger footprint and higher BOM, while RL78/G13 provides superior power efficiency and modern toolchain support but demands complete software rework - neither is pin-compatible.

Yes, the M30281F6HP#UFB integrates a 10-bit successive-approximation ADC with 8 input channels, internal reference voltage, and conversion time of 12.5 µs. Inputs are mapped to Port 1 pins P14–P17 and Port 2 pins P20–P23, supporting simultaneous sampling in scan mode.
What package type is used for the M30281F6HP#UFB?
The M30281F6HP#UFB is housed in a 52-pin LQFP package (10 mm × 10 mm, 0.65 mm pitch) with exposed thermal pad. This RoHS-compliant package supports standard reflow profiles and provides 42 general-purpose I/O pins plus dedicated power, clock, and reset terminals.
Can the M30281F6HP#UFB operate from a 3.3 V supply?
Yes, the M30281F6HP#UFB operates across a supply voltage range of 2.7 V to 5.5 V, making it fully compatible with 3.3 V systems. At 3.3 V, it maintains full functionality including Flash programming, ADC operation, and 20 MHz CPU performance - no derating required.
Is there a built-in watchdog timer in the M30281F6HP#UFB?
Yes, the M30281F6HP#UFB includes a hardware watchdog timer with an independent 15 kHz on-chip oscillator and windowed operation mode.
