Overview
M30876FJGP#U3 from Renesas Electronics is a 100-pin LQFP flash-based 16-bit MCU in the M32C/87A family, featuring an M32C/80 CPU core, 512 KB on-chip flash ROM + 4 KB data flash, 31 KB RAM, dual CAN 2.0B channels (M32C/87 variant), and integrated peripherals including 10-bit ADC (26 ch), dual 8-bit DAC, UARTs × 6, I²C, and 3-phase motor control timers - deployed in industrial automation controllers requiring deterministic real-time response.
For engineers reviewing the M30876FJGP#U3 datasheet, M30876FJGP#U3 pinout, M30876FJGP#U3 application, or M30876FJGP#U3 equivalent, key selection criteria include its 100-pin PLQP0100KB-A package, 32 MHz operation at 4.2–5.5 V, CAN 2.0B dual-channel support, and compatibility with Renesas' M32C development tools and on-chip debug interface.
Technical Context
The M30876FJGP#U3 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 (1–7), 4 chip selects, and dual-voltage (3 V/5 V) interface capability.
Timing subsystem includes four independent clock sources (main, sub, on-chip oscillator, PLL), programmable frequency division (ratios 1–16), and low-power modes (wait, stop). Interrupt architecture supports 70 vectors, 11 external inputs (NMI, INT×6, key×4), and 7 priority levels - enabling responsive real-time task scheduling in embedded control systems.

FAQ
What is the maximum operating frequency and voltage range for the M30876FJGP#U3?
The M30876FJGP#U3 operates at up to 32 MHz with VCC1 supply between 4.2 V and 5.5 V, or at 24 MHz with VCC1 from 3.0 V to 5.5 V. VCC2 must be maintained between 3.0 V and VCC1. These ranges are specified in the REJ03B0127-0151 datasheet Rev. 1.51 and define the valid conditions for achieving rated performance and timing compliance in the M30876FJGP#U3.
Does the M30876FJGP#U3 support CAN 2.0B, and how many channels are implemented?
Yes, the M30876FJGP#U3 implements two independent CAN 2.0B-compliant channels, each with 16 message mailboxes. This configuration is confirmed in Table 1.2 of the M32C/87 Group datasheet (REJ03B0127-0151), where M30876FJGP#U3 is classified under the M32C/87 variant - distinct from M32C/87A (single CAN) and M32C/87B (no CAN). The CAN0 and CAN1 pins are assigned to specific port pins (e.g., P8_2/P8_3, P9_5/P9_6) in the 100-pin LQFP package.
What package type and pin count does the M30876FJGP#U3 use?
The M30876FJGP#U3 uses a 100-pin plastic LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch), as documented in Table 1.6 of the REJ03B0127-0151 datasheet. This matches the "GP" suffix in the part number and distinguishes it from 144-pin variants like M30878FJGP. The package supports standard surface-mount assembly and thermal dissipation requirements for industrial ambient temperatures (−20°C to +85°C).
How much on-chip memory does the M30876FJGP#U3 include, and what types are available?
The M30876FJGP#U3 integrates 512 KB of on-chip flash ROM plus 4 KB of dedicated data flash memory for parameter storage, along with 31 KB of RAM. This memory configuration is explicitly listed in Table 1.6 (M32C/87 Group Product List) of the REJ03B0127-0151 datasheet. The flash supports in-system programming via on-chip debug, and security features include ROM code protection and ID code verification.
Is the M30876FJGP#U3 compatible with Renesas' standard development tools and debug interfaces?
Yes, the M30876FJGP#U3 supports Renesas' E1/E20 emulators and the CS+ IDE via its on-chip debug interface, which uses a single-wire SWD connection. Debug capabilities include real-time program execution control, register and memory inspection, flash programming, and breakpoint management - all confirmed in Section 1.1.2 (Specifications) and Section 2.3 (Debug Functions) of the REJ03B0127-0151 datasheet for the M32C/87 Group.
