Product details
Overview
M30280FATHP#U3 from Renesas Electronics is a 16-bit CMOS microcontroller in the M16C/28 Group, designed for embedded control in industrial and consumer systems. It features 256 KB on-chip flash memory, 16 KB RAM, a 16-MHz max CPU clock, 8-channel 10-bit ADC, and integrated UART, I²C, and timer peripherals. It targets motor control, power supply management, and appliance control applications.
For engineers reviewing the M30280FATHP#U3 datasheet, M30280FATHP#U3 pinout, M30280FATHP#U3 application, or M30280FATHP#U3 equivalent, key selection criteria include its 100-pin LQFP package, 3.0–5.5 V operating voltage, −40 to +85 °C industrial temperature range, flash endurance of 10,000 write/erase cycles, and support for on-chip debugging via JTAG interface.
Technical Context
The M30280FATHP#U3 implements the M16C CPU core with 16-bit data bus and 24-bit address space, supporting both single-cycle and multi-cycle instruction execution. It integrates a programmable watchdog timer, oscillation stop detection with automatic recovery, and four power-saving modes (Wait, Stop, Sub-clock Wait, and Deep Stop) controlled via dedicated system control registers.
Peripheral integration includes three 16-bit timer arrays (each with capture/compare/PWM functions), two serial interface modules (UART/SIO capable of IrDA modulation), and an 8-channel analog-to-digital converter with sample-and-hold and hardware-triggered conversion sequencing. All peripherals are memory-mapped and accessible via dedicated SFRs with configurable interrupt vectors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21285SDFP#30 | Same M16C/28 core, but with 128 KB flash, 8 KB RAM, and no IEBus support; uses same 100-pin LQFP package | Lacks IEBus interface and reduced memory-suitable only where legacy bus compatibility is not required | Select when cost reduction is prioritized and full 256 KB flash is unnecessary |
| RL78/G13 R5F100LEAFB#30 | Successor RL78 core with lower power (66 μA/MHz), 128 KB flash, 12 KB RAM, and enhanced ADC (12-bit, 21 channels) | Higher integration (capacitive touch, LIN, DMA) but requires PCB redesign due to different pinout and 64-pin QFP package | Choose for new designs targeting extended battery life and future-proof peripheral needs |
Compared with R5F21285SDFP#30, M30280FATHP#U3 offers double flash capacity and IEBus support for automotive audio systems; compared with RL78/G13 R5F100LEAFB#30, it retains legacy software compatibility but consumes more active power and lacks capacitive touch capability.

FAQ
What is the maximum operating frequency of the M30280FATHP#U3?
The M30280FATHP#U3 supports a maximum CPU clock frequency of 16 MHz, achievable via its on-chip PLL when driven by a 4 MHz external crystal or oscillator. This frequency is guaranteed across the full industrial temperature range (−40 to +85 °C) and 3.0–5.5 V supply voltage. The M30280FATHP#U3 also supports lower-frequency operation down to DC for ultra-low-power applications using its sub-clock mode.
Does the M30280FATHP#U3 support in-system programming (ISP)?
Yes, the M30280FATHP#U3 supports in-system programming via its on-chip bootloader accessed through UART or I²C interfaces. Firmware updates can be performed without removing the device from the target board, provided the host system implements the Renesas-standard command protocol. The M30280FATHP#U3 bootloader resides in protected ROM and remains functional even after flash lock bits are set.
What debug interface does the M30280FATHP#U3 provide?
The M30280FATHP#U3 includes a standard 5-pin JTAG interface (TCK, TMS, TDO, TDI, TRST) compliant with IEEE 1149.1, enabling full boundary-scan testing, real-time debugging, and flash programming. Renesas' E8/E8a emulators and compatible third-party tools support non-intrusive breakpoint setting, register inspection, and memory dump during live execution of the M30280FATHP#U3.
Is the M30280FATHP#U3 qualified for automotive applications?
No, the M30280FATHP#U3 is rated as a Standard-grade device per Renesas' quality classification and is intended for industrial and consumer applications such as appliances and factory equipment. It is not AEC-Q100 qualified, lacks automotive-specific qualification testing (e.g., HTOL, ESD, EMC), and does not meet the failure-in-time (FIT) requirements for automotive ECUs. For automotive use, Renesas recommends the RH850 or RL78/F1x families instead of the M30280FATHP#U3.
What peripheral interfaces are integrated into the M30280FATHP#U3?
The M30280FATHP#U3 integrates UART (2 channels), I²C (1 channel), serial I/O (SIO) supporting IrDA and synchronous protocols, 16-bit timer arrays (3 modules), 10-bit ADC (8 channels), watchdog timer, and IEBus interface. It also supports JTAG for debugging and has GPIO with configurable pull-ups/pull-downs. No CAN, USB, or Ethernet peripherals are included-the M30280FATHP#U3 relies on external transceivers for fieldbus extension.
