Renesas M30828MH-XXXGP#U3

Overview

M30828MH-XXXGP#U3 from Renesas Electronics is a 144-pin LQFP masked-ROM 16/32-bit microcontroller in the M32C/82 Group, featuring a 384 KB ROM, 24 KB RAM, 123 I/O pins, 10-bit A/D converter (34 channels), and dual 8-bit D/A converters. It executes instructions in as little as 33 ns at 30 MHz and supports single-chip, memory expansion, and microprocessor modes for office automation, industrial equipment, and camera control systems.

For engineers reviewing the M30828MH-XXXGP#U3 datasheet, M30828MH-XXXGP#U3 pinout, M30828MH-XXXGP#U3 application, or M30828MH-XXXGP#U3 equivalent, key selection criteria include its 144-pin LQFP package, 384 KB masked ROM capacity, 10-bit 34-channel ADC, DMAC with chain transfer capability, and support for IEBus, I²C, and HDLC serial protocols in embedded real-time control applications.

Technical Context

The M30828MH-XXXGP#U3 implements the M32C/80 series CPU core with 108 basic instructions and a 16-Mbyte address space. Its clock system includes main/sub crystal oscillators, on-chip oscillator, and PLL frequency synthesizer - all with built-in feedback resistors requiring external crystals or ceramic resonators.

It integrates five peripheral timer groups (Timer A ×5, Timer B ×6), intelligent I/O with 12 time-measurement and 20 waveform-generation channels, and a three-phase motor control circuit. The device lacks CAN, A/D1 converter, and Intelligent I/O Group 3 found in the M32C/83 Group, limiting its use to non-automotive industrial and consumer applications.

FAQ

What is the ROM type and capacity of the M30828MH-XXXGP#U3?

The M30828MH-XXXGP#U3 contains 384 KB of factory-masked ROM, which is programmed during wafer fabrication and cannot be electrically erased or reprogrammed. This provides firmware security and immunity to accidental corruption in harsh industrial environments. The M30828MH-XXXGP#U3 uses masked ROM exclusively - no Flash or EEPROM is integrated.

Does the M30828MH-XXXGP#U3 support CAN bus communication?

No, the M30828MH-XXXGP#U3 does not support CAN bus communication. According to the official Renesas documentation, CAN functionality is explicitly excluded from the M32C/82 Group - it is only available in the higher-integration M32C/83 Group. Engineers requiring CAN must select an M32C/83-series part or add an external CAN controller.

What is the maximum operating frequency and corresponding supply voltage for the M30828MH-XXXGP#U3?

The M30828MH-XXXGP#U3 achieves a shortest instruction execution time of 33 ns at 30 MHz, requiring a supply voltage of 4.2 V to 5.5 V. At lower frequencies (20 MHz), it supports 3.0 V to 5.5 V operation when using the VDC path, or 3.0 V to 3.6 V without VDC - enabling flexible power design across multiple rail configurations.

How many analog-to-digital converter channels does the M30828MH-XXXGP#U3 support?

The M30828MH-XXXGP#U3 integrates a single 10-bit A/D converter with up to 34 input channels, including dedicated analog inputs (AN0–AN27, AN30–AN37, ANEX0/ANEX1) and multiplexed port pins. Channel selection is software-configurable via the AD control register, and conversion can be triggered by internal timers or external signals like ADTRG on pin P97.

Is the M30828MH-XXXGP#U3 pin-compatible with other M32C/82 Group members?

Yes, the M30828MH-XXXGP#U3 shares the same 144-pin LQFP (144P6Q-A) package and pinout with other 144-pin M32C/82 Group variants such as M30825MH-XXXGP and M30825MW-XXXGP. Pin assignments, electrical characteristics, and peripheral mappings are identical across this package family, enabling drop-in replacement within the same footprint.
