Product details
Overview
M30878FJBGP#U5 from Renesas Electronics is a 144-pin LQFP flash-based 16-bit MCU in the M32C/87B family, embedding the M32C/80 CPU core with 512 KB + 4 KB data flash, 31 KB RAM, dual CAN 2.0B modules (disabled in 87B variant), and integrated peripherals including 10-bit ADC (34 channels), 8-bit DAC (2 channels), and 16-bit timers for motor control. It targets industrial automation and office equipment requiring deterministic real-time control.
For engineers reviewing the M30878FJBGP#U5 datasheet, M30878FJBGP#U5 pinout, M30878FJBGP#U5 application, or M30878FJBGP#U5 equivalent, key selection criteria include its 144-pin PLQP0144KA-A package, 32 MHz max operation at 4.2–5.5 V, CAN module exclusion (M32C/87B), on-chip debug support, and -20 to 85°C operating range.
Technical Context
The M30878FJBGP#U5 implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit), supporting single-chip, memory expansion, and microprocessor modes. Its external bus interface provides 16-Mbyte address space with configurable wait states, 4 chip selects, and 3V/5V I/O compatibility.
It integrates dual independent DMAC units (DMAC and DMACII), 7-channel UARTs (including IrDA and I²C modes), CRC-CCITT calculation circuit, X/Y converter, and intelligent I/O with input capture (8 channels) and output compare (16 channels). The device lacks CAN functionality per M32C/87B specification.

FAQ
What is the CAN capability of the M30878FJBGP#U5?
The M30878FJBGP#U5 belongs to the M32C/87B subfamily and has no functional CAN modules. Although CAN-related pins (e.g., P8_2, P8_3, P9_5, P9_6) are physically present on the 144-pin LQFP package, they are disabled per Renesas specification and must not be used for CAN communication. M30878FJBGP#U5 retains full UART, I²C, and intelligent I/O functionality for alternative serial protocols.
Does the M30878FJBGP#U5 support on-chip debug and flash programming?
Yes, the M30878FJBGP#U5 includes full on-chip debug capability and on-board flash reprogramming support. Engineers can perform real-time debugging, breakpoint insertion, and firmware updates via the dedicated debug interface without external emulators. This feature is confirmed in the Renesas REJ03B0127-0151 datasheet section 1.1.2 and applies directly to M30878FJBGP#U5 as a flash-memory variant.
What is the maximum operating frequency and supply voltage range for M30878FJBGP#U5?
The M30878FJBGP#U5 operates at up to 32 MHz when supplied with VCC1 = 4.2–5.5 V and VCC2 = 3.0 V to VCC1. At 24 MHz, it supports a wider VCC1 range of 3.0–5.5 V. These specifications are explicitly defined in Tables 1.1 and 1.3 of the official Renesas datasheet REJ03B0127-0151 Rev.1.51 and apply to the M30878FJBGP#U5 144-pin flash variant.
How many ADC channels does the M30878FJBGP#U5 provide, and what is their resolution?
The M30878FJBGP#U5 provides 34 channels of 10-bit analog-to-digital conversion in single-chip mode, with built-in sample-and-hold functionality. This count is specific to the 144-pin package and is documented in Table 1.1 (144-pin specs) of the Renesas REJ03B0127-0151 datasheet. Channel mapping includes AN0_0 through AN15_7 and dedicated analog inputs on Ports P9–P15.
Is the M30878FJBGP#U5 pin-compatible with other M32C/87 Group members?
The M30878FJBGP#U5 shares the same 144-pin PLQP0144KA-A package and pinout with other 144-pin M32C/87 Group variants (e.g., M3087BFLGP, M30878FJGP), but functional differences exist-especially CAN module presence/absence and flash configuration. While mechanical mounting is identical, firmware and schematic design must account for disabled CAN pins and variant-specific memory maps in M30878FJBGP#U5.
