It operates at up to 20 MHz CPU clock and supports industrial temperature range (−40°C to +85°C) in a 100-pin LQFP package. It is used in motor control, industrial automation, and embedded HMI systems.

For engineers reviewing the M30280FAWG#U7B datasheet, M30280FAWG#U7B pinout, M30280FAWG#U7B application, or M30280FAWG#U7B equivalent, key selection criteria include flash endurance (10,000 write/erase cycles), low-power stop/wait modes, hardware multiplier support, and compatibility with Renesas' M16C development tools and C compiler suite.

Technical Context

The M30280FAWG#U7B implements the M16C CPU core with 16-bit data bus and 24-bit address space, supporting both big-endian and little-endian data access via software configuration. It integrates a programmable watchdog timer, voltage detection circuit for brown-out reset, and oscillation stop detection with automatic re-oscillation recovery interrupt capability.

Its peripheral set includes three 16-bit timer modules (TMR0–TMR2) with capture/compare/PWM output, one serial interface (SIO) configurable as UART or I²C master/slave, and a 10-channel 10-bit successive-approximation ADC with internal reference and scan mode. Clock generation supports main crystal (1–20 MHz), sub-crystal (32.768 kHz), and on-chip oscillator options with PLL multiplication up to 80 MHz internal clock.

FAQ

What is the maximum operating frequency of the M30280FAWG#U7B?

The M30280FAWG#U7B supports a maximum CPU clock frequency of 20 MHz. Its internal PLL can generate an 80 MHz clock for peripheral timing, but the core executes instructions at the 20 MHz rate. This frequency is guaranteed across the full industrial temperature range (−40°C to +85°C) and 2.7–5.5 V supply voltage. The M30280FAWG#U7B achieves this using either an external crystal (1–20 MHz on XT1/XT2) or the on-chip oscillator with PLL multiplication.

Does the M30280FAWG#U7B include on-chip debug capability?

Yes, the M30280FAWG#U7B features a fully integrated on-chip debug interface compliant with Renesas' standard debug protocol. It supports real-time trace, breakpoint setting, and memory/register inspection using Renesas E8 or E8a debug emulators. No external debug hardware is required beyond the emulator and JTAG/SWD connector. This capability is enabled by default and does not consume user flash or RAM resources in the M30280FAWG#U7B.

What ADC resolution and channel count does the M30280FAWG#U7B provide?

The M30280FAWG#U7B integrates a 10-bit successive-approximation ADC with 10 input channels (AD0–AD9), multiplexed onto Port 2 pins. It supports internal 2.5 V reference voltage, software-triggered or timer-triggered conversion, and auto-scan mode for sequential channel sampling. Conversion time is 1.5 µs per channel at maximum clock, and the ADC module includes dedicated result registers and interrupt flags per channel in the M30280FAWG#U7B.

Is the M30280FAWG#U7B pin-compatible with other M16C/28 devices?

Yes, the M30280FAWG#U7B is pin-compatible with all members of the M16C/28 Group sharing the 100-pin LQFP package (e.g., M30280FAXG#U7B, M30280FASG#U7B). Pin assignments for power, reset, clock, I/O ports, and peripheral functions are identical across this package variant. Firmware migration between these parts requires only flash size and peripheral enable register adjustments-no PCB changes are needed for the M30280FAWG#U7B.

What is the flash endurance specification for the M30280FAWG#U7B?

The M30280FAWG#U7B specifies 10,000 write/erase cycles for its 256 KB on-chip flash memory, with data retention guaranteed for 20 years at 85°C. Block erase granularity is 128 bytes, enabling efficient firmware patching and parameter storage. Flash programming is supported via on-chip bootloader or external programmer using Renesas' standard FL-PRG protocol. This endurance rating applies under recommended operating conditions and is validated per JEDEC JESD22-A117.
