Product details
Overview
M30826MH-XXXGP from Renesas Electronics is a masked-ROM 16/32-bit microcontroller in the M32C/82 Group, featuring a 384 KB ROM and 31 KB RAM, 100-pin LQFP package, 10-bit A/D converter (26 channels), dual 8-bit D/A converters, and 5-channel serial I/O including IEBus and I²C. It executes instructions in as little as 33 ns at 30 MHz and targets office automation, industrial control, and portable equipment.
For engineers reviewing the M30826MH-XXXGP datasheet, M30826MH-XXXGP pinout, M30826MH-XXXGP application, or M30826MH-XXXGP equivalent, key selection criteria include its 100-pin LQFP footprint, 384 KB/31 KB memory configuration, 10-bit ADC with 26 inputs, support for IEBus and I²C interfaces, and operation across –20°C to +85°C ambient temperature.
Technical Context
The M30826MH-XXXGP 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 complex embedded firmware deployment without external memory in many applications.
It integrates four clock generation circuits - main/sub crystal oscillators, on-chip oscillator, and PLL frequency synthesizer - with built-in feedback resistors requiring external ceramic resonators or crystals. The device lacks CAN and intelligent I/O group 3 found in the M32C/83 Group, confirming its targeted role in cost-optimized, non-automotive control systems.

FAQ
What is the maximum operating frequency and corresponding supply voltage for the M30826MH-XXXGP?
The M30826MH-XXXGP 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 voltages (3.0 V to 5.5 V), the maximum supported frequency is 20 MHz with a 50 ns instruction time. This dual-voltage/frequency profile allows flexible trade-offs between performance and power consumption in battery- or adapter-powered systems.
Does the M30826MH-XXXGP support CAN bus communication?
No, the M30826MH-XXXGP does not include a CAN controller. As documented in the M32C/82 Group datasheet, CAN and intelligent I/O group 3 are explicitly excluded from this family - features reserved for the higher-end M32C/83 Group. Designers requiring CAN must select an M32C/83 variant or add an external CAN transceiver with software protocol handling.
How many analog input channels does the M30826MH-XXXGP's 10-bit A/D converter support?
The M30826MH-XXXGP integrates one 10-bit A/D converter supporting 26 analog input channels. These are mapped across dedicated pins including AN0–AN7 (P00–P07), AN20–AN27 (P20–P27), and AN30–AN37 (P100–P107), enabling simultaneous monitoring of multiple sensors in compact industrial or instrumentation designs.
What clock sources are built into the M30826MH-XXXGP?
The M30826MH-XXXGP includes four integrated clock sources: main clock oscillator (XIN/XOUT), sub-clock oscillator (XCIN/XCOUT), on-chip RC oscillator, and PLL frequency synthesizer. The main and sub oscillators feature built-in feedback resistors, eliminating external bias components when using ceramic resonators or crystals - reducing BOM count and layout complexity.
Is the M30826MH-XXXGP pin-compatible with other members of the M32C/82 Group?
Yes, the M30826MH-XXXGP shares identical pinout and electrical characteristics with other 100-pin LQFP variants in the M32C/82 Group, including M30823MH-XXXGP and M30823MW-XXXGP. All use the 100P6Q-A package and maintain consistent signal assignments across power, I/O, analog, and serial interface pins - enabling drop-in replacement where memory requirements align.
