Product details
Overview
M30280FCHP#U5B from Renesas Electronics is a 16-bit single-chip microcontroller in the M16C/28 Group, designed for embedded control applications requiring integrated peripherals, low-power operation, and industrial-grade reliability. It features 256 KB on-chip Flash memory, 16 KB RAM, a 16-bit CPU core, 54 I/O pins, and supports operating frequencies up to 20 MHz at 3.0–5.5 V supply. It is used in motor control systems, industrial PLC modules, and sensor interface units.
For engineers reviewing the M30280FCHP#U5B datasheet, M30280FCHP#U5B pinout, M30280FCHP#U5B application, or M30280FCHP#U5B equivalent, key selection criteria include Flash endurance (10,000 write/erase cycles), built-in voltage detection circuit (2.7 V threshold), watchdog timer with window function, and support for both main clock (1–20 MHz crystal) and sub-clock (32.768 kHz) sources.
Technical Context
The M30280FCHP#U5B implements the M16C CPU architecture with 16-bit data bus and 24-bit address space, enabling direct access to its full 256 KB Flash and 16 KB RAM without banking. Its clock generation circuit integrates PLL, on-chip oscillator, and oscillation stop detection - allowing dynamic switching between normal, wait, and stop modes with sub-μA current draw in stop mode.
Peripheral integration includes three 16-bit timer/counters (with PWM output), two UARTs with IrDA support, one I2C-compatible serial interface, 10-bit ADC with 16 channels, and dedicated IE-Bus controller for automotive body electronics communication. All peripherals are memory-mapped and controlled via Special Function Registers (SFRs) with interrupt capability.

FAQ
What is the maximum operating frequency supported by the M30280FCHP#U5B?
The M30280FCHP#U5B supports a maximum CPU clock frequency of 20 MHz, achievable via its on-chip PLL when driven by an external 1–20 MHz crystal connected to XT1/XT2. This frequency is fully specified across the 3.0–5.5 V supply range and ambient temperature of −40°C to +85°C, enabling deterministic real-time control in motor drive and industrial automation applications using the M30280FCHP#U5B.
Does the M30280FCHP#U5B include a hardware watchdog timer with window functionality?
Yes, the M30280FCHP#U5B integrates a windowed watchdog timer (WDT) that requires refresh within a defined time window - not just before timeout. This prevents both software lockup and premature or periodic resets caused by runaway code. The WDT operates independently of the main clock and remains functional in wait mode, enhancing system reliability in unattended M30280FCHP#U5B deployments.
Can the M30280FCHP#U5B operate from a 3.3 V supply, and is it 5 V tolerant?
Yes, the M30280FCHP#U5B operates across a 3.0–5.5 V supply range, making it fully compatible with 3.3 V systems. Its I/O pins are 5 V tolerant when VCC ≥ 4.5 V, but not when powered at 3.3 V. For mixed-voltage interfacing at 3.3 V, external level shifters or resistor dividers are recommended. This dual-voltage capability simplifies integration into both legacy 5 V and modern 3.3 V M30280FCHP#U5B-based designs.
What communication interfaces are integrated into the M30280FCHP#U5B?
The M30280FCHP#U5B integrates two UARTs (one with IrDA support), one I2C-compatible serial interface, and a dedicated hardware IE-Bus controller compliant with the NEC IE-Bus specification. These interfaces support simultaneous use - for example, UART0 for host diagnostics, UART1 for Modbus RTU, and IE-Bus for automotive body network communication - all managed without CPU intervention via DMA or interrupt-driven SFRs in the M30280FCHP#U5B.
Is there on-chip Flash memory endurance data available for the M30280FCHP#U5B?
Yes, the M30280FCHP#U5B specifies 10,000 write/erase cycles for its 256 KB on-chip Flash memory under standard operating conditions (Ta = 25°C, VCC = 5.0 V). Endurance is guaranteed across the full industrial temperature range when adhering to Renesas' programming timing requirements. This allows reliable field firmware updates and parameter storage in M30280FCHP#U5B-based products with multi-year service lifetimes.
