Product details
Overview
M30876MJ-XXXFP from Renesas Electronics is a 100-pin mask ROM-based 16-bit MCU in the M32C/87A family, featuring the M32C/80 CPU core, 512 KB ROM, 31 KB RAM, CAN 2.0B-compliant single-channel controller, and 26-channel 10-bit ADC - deployed in office equipment, industrial motor control, and communication devices.
For engineers reviewing the M30876MJ-XXXFP datasheet, M30876MJ-XXXFP pinout, M30876MJ-XXXFP application, or M30876MJ-XXXFP equivalent, key selection criteria include its 100-pin QFP package (PRQP0100JB-A), single CAN channel support, 24–32 MHz operation across 3.0–5.5 V supply, on-chip debug capability, and compatibility with Renesas' M32C development tools and flash-programmable variants.
Technical Context
The M30876MJ-XXXFP implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit), supporting single-chip, memory expansion, and microprocessor operating modes. Its external bus interface provides 16-Mbyte address space with configurable wait states, 4 chip selects, and dual-voltage (3 V/5 V) I/O support.
It integrates dual DMA controllers (DMAC and DMACII), seven UARTs (including IrDA and IEBus options), 16-bit Timer A ×5 and Timer B ×6, 3-phase motor control logic using TA1–TA4 and TB2, and an on-chip dead-time timer - all synchronized via four clock sources: main/sub oscillators, on-chip oscillator, and PLL frequency synthesizer.

Equivalent & Alternatives
The following parts are listed as comparable options for similar MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M30876FJGP | Same 100-pin LQFP package, identical pinout, but uses flash memory (768 KB + 4 KB data flash) instead of mask ROM | Enables field firmware updates and prototyping; requires external programming infrastructure | Select when design flexibility, post-deployment updates, or low-volume production justify higher unit cost and longer programming time |
| M30876MJA-XXXFP | Identical mask ROM configuration (512 KB/31 KB), same PRQP0100JB-A package, but belongs to M32C/87A family with one CAN channel - functionally identical | No functional difference; "MJA" denotes same silicon revision and qualification level as "MJ" | Select when sourcing newer-date-code stock or aligning with Renesas' current part-numbering convention |
Compared with M30876MJ-XXXFP, M30876FJGP adds field-reprogrammability at the cost of erase endurance limits and higher BOM complexity, while M30876MJA-XXXFP offers identical functionality under updated nomenclature - both retain the same 100-pin QFP footprint, CAN 2.0B support, and motor-control peripherals.

FAQ
What is the maximum operating frequency of the M30876MJ-XXXFP and at what supply voltage?
The M30876MJ-XXXFP operates up to 32 MHz when VCC1 is maintained between 4.2 V and 5.5 V. At lower supply voltages (3.0 V to 5.5 V), the maximum guaranteed frequency is 24 MHz. These ratings are defined in the electrical characteristics section of the REJ03B0127-0151 datasheet, and the M30876MJ-XXXFP must be operated within these voltage-frequency boundaries to ensure correct instruction execution and peripheral timing.
Does the M30876MJ-XXXFP include on-chip debug capability?
Yes, the M30876MJ-XXXFP includes full on-chip debug support compatible with Renesas E8/E8a emulators and CS+ IDE. This allows real-time program execution control, register inspection, memory read/write, and flash programming - all without requiring external boundary-scan hardware. The M30876MJ-XXXFP debug interface is accessible via dedicated pins and does not consume user I/O resources.
How many CAN channels does the M30876MJ-XXXFP support, and which CAN specification is implemented?
The M30876MJ-XXXFP supports one CAN channel compliant with the ISO 11898-1:2003 CAN 2.0B specification, including full 29-bit identifier support and error confinement. As an M32C/87A variant, it lacks the second CAN channel present in the M32C/87 version. The M30876MJ-XXXFP's CAN peripheral integrates message RAM, acceptance filtering, and automatic retransmission - eliminating need for external CAN protocol controllers.
What package type and pin count does the M30876MJ-XXXFP use?
The M30876MJ-XXXFP is housed in a 100-pin plastic quad flat pack (QFP) with JEDEC MO-137 outline, designated PRQP0100JB-A. It features 0.65 mm lead pitch, 14 mm × 14 mm body size, and standard gull-wing leads. This package is distinct from the 144-pin LQFP used by higher-pin-count M32C/87 variants, and the M30876MJ-XXXFP pinout is not compatible with 144-pin versions.
Is the M30876MJ-XXXFP mask ROM programmable after manufacturing?
No, the M30876MJ-XXXFP contains factory-programmed mask ROM and cannot be reprogrammed in-system or during production. Its 512 KB program memory is permanently fixed at wafer fabrication. For designs requiring field updates or iterative firmware development, Renesas offers pin-compatible flash-based alternatives such as M30876FJGP - but the M30876MJ-XXXFP itself delivers cost-optimized, tamper-resistant code storage for high-volume, mature applications.
