Renesas M30826MH-XXXFP#U0

Overview

M30826MH-XXXFP#U0 from Renesas Electronics is a masked-ROM-based 16/32-bit microcontroller in the M32C/82 Group, featuring a 384 KB ROM, 31 KB RAM, and 100-pin plastic molded QFP (100P6S-A) package. It executes instructions in as little as 33 ns at 30 MHz, integrates a 10-bit A/D converter with 26 channels, dual 8-bit D/A converters, 4-channel DMAC, and five serial I/O interfaces including IEBus and I²C for embedded control in office equipment and industrial systems.

For engineers reviewing the M30826MH-XXXFP#U0 datasheet, M30826MH-XXXFP#U0 pinout, M30826MH-XXXFP#U0 application, or M30826MH-XXXFP#U0 equivalent, key selection criteria include its 100-pin LQFP footprint, 384 KB masked ROM capacity, 26-channel 10-bit ADC, support for wait/stop low-power modes (down to 0.4 µA), and absence of CAN or intelligent I/O group 3-critical for timing-critical motor control and communication subsystems.

Technical Context

The M30826MH-XXXFP#U0 implements the M32C/80 series CPU core with 108 basic instructions and supports single-chip, memory expansion, and microprocessor operation modes. Its 16-Mbyte address space enables scalable firmware architecture, while integrated peripherals-including Timer A (5×16-bit), Timer B (6×16-bit), three-phase motor control circuit, and HDLC data processing-target real-time deterministic control.

It features four independent clock generation circuits: main crystal oscillator (with external crystal/resonator), sub-clock oscillator, on-chip oscillator, and PLL frequency synthesizer. Oscillation stop detection on the main clock ensures fail-safe reset behavior. The device excludes CAN, intelligent I/O group 3, and A/D1 converter-differentiating it from the higher-function M32C/83 Group.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the M30826MH-XXXFP#U0?

The M30826MH-XXXFP#U0 achieves a maximum bus clock (BCLK) frequency of 30 MHz at a supply voltage of 4.2–5.5 V. At reduced supply voltages (3.0–3.6 V), the maximum supported BCLK is 20 MHz. These ratings are validated per the Renesas M32C/82 Group datasheet Rev.1.20, and operation outside these ranges may result in undefined behavior or timing violations.

Does the M30826MH-XXXFP#U0 include CAN interface capability?

No, the M30826MH-XXXFP#U0 does not include CAN peripheral hardware. As explicitly stated in the M32C/82 Group documentation, CAN is excluded from this family-unlike the M32C/83 Group. Engineers requiring CAN must select alternate MCUs such as the M30624FGFP or migrate to the RL78/F1x series, as the M30826MH-XXXFP#U0 lacks both CAN registers and physical CAN transceiver pins.

How many analog-to-digital converter channels does the M30826MH-XXXFP#U0 support, and what is their resolution?

The M30826MH-XXXFP#U0 integrates a single 10-bit successive-approximation A/D converter with 26 configurable input channels. These include AN0–AN7, AN20–AN27, AN150–AN157, and AN30–AN37 (depending on package variant), all sharing the same 10-bit conversion engine. Conversion time is 1.5 µs per channel at maximum clock rate, as confirmed in Table 1.2 of the official Renesas documentation.

What package type and pin count does the M30826MH-XXXFP#U0 use, and is it RoHS-compliant?

The M30826MH-XXXFP#U0 uses the 100-pin plastic molded QFP package designated 100P6S-A, with 0.65 mm lead pitch and dimensions of 14 × 20 mm. Per Renesas' environmental compliance statements, this package is RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU requirements without exemptions.

Is the M30826MH-XXXFP#U0 pin-compatible with other members of the M32C/82 Group, such as the M30823MH-XXXFP?

Yes, the M30826MH-XXXFP#U0 is fully pin-compatible with the M30823MH-XXXFP and M30823MW-XXXFP in the 100P6S-A package. All share identical pin assignments, electrical characteristics, and mechanical footprint-enabling drop-in replacement where firmware and memory requirements align. This compatibility is verified in Figures 1.5 and 1.6 of the Renesas M32C/82 Group datasheet Rev.1.20.
