Product details
Overview
M30878FJBGP#U3 from Renesas Electronics is a 144-pin LQFP flash-based 16-bit MCU in the M32C/87B family, featuring the M32C/80 CPU core, 512 KB + 4 KB data flash, 31 KB RAM, dual CAN 2.0B modules (disabled in M32C/87B), and operation up to 32 MHz at 4.2–5.5 V. It targets industrial motor control and embedded automation requiring integrated timers, ADC, and serial interfaces.
For engineers reviewing the M30878FJBGP#U3 datasheet, M30878FJBGP#U3 pinout, M30878FJBGP#U3 application, or M30878FJBGP#U3 equivalent, key selection criteria include its 144-pin PLQP0144KA-A package, 34-channel 10-bit ADC (144-pin config), on-chip PLL and four clock sources, 5 UARTs with IrDA/IEBus support, and CAN module exclusion per M32C/87B specification.
Technical Context
The M30878FJBGP#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 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 two independent DMAC units: DMAC (4 channels, cycle-steal) and DMACII (burst/single transfer, chain/calculation functions), plus five 16-bit Timer A units with PWM and 2-phase encoder input, six 16-bit Timer B units for pulse measurement, and dedicated 3-phase motor control logic using TA1–TA4 and TB2.

FAQ
Does M30878FJBGP#U3 support CAN communication?
No, M30878FJBGP#U3 belongs to the M32C/87B variant, which explicitly excludes CAN modules per Renesas documentation (Table 1.7 and Note 5 in Figure 1.2). While CAN-related pins (e.g., P8_2, P8_3) exist on the 144-pin package, they are unconnected internally and must not be used for CAN signaling. The part number suffix "B" definitively indicates zero CAN channels.
What is the operating temperature range for M30878FJBGP#U3?
M30878FJBGP#U3 is rated for -40°C to +85°C ambient operation, as confirmed by Renesas REJ03B0127-0151 Rev.1.51 Table 1.2 and Table 1.4 under "Operating Ambient Temperature." The "#U3" suffix denotes this extended industrial temperature grade, distinguishing it from standard -20°C to +85°C variants like M30878FJGP.
How much flash memory does M30878FJBGP#U3 include?
M30878FJBGP#U3 integrates 512 KB of main program flash memory plus an additional 4 KB of dedicated data flash memory, as specified in Table 1.7 of the Renesas datasheet. This data flash is erasable/programmable independently and is intended for storing calibration constants, device configuration, or field-upgradeable parameters.
Which package type is used by M30878FJBGP#U3?
M30878FJBGP#U3 uses the 144-pin LQFP package designated PLQP0144KA-A (also referenced as 144P6Q-A), with 20 mm × 20 mm body size and 0.5 mm lead pitch. This is confirmed in Table 1.7 and Figure 1.3 of the Renesas datasheet REJ03B0127-0151 Rev.1.51.
Does M30878FJBGP#U3 include a hardware multiplier?
Yes, M30878FJBGP#U3 incorporates a hardware 16-bit × 16-bit → 32-bit multiplier as part of the M32C/80 CPU core, enabling single-cycle multiply-add operations (16×16+48→48 bits). This accelerates motor control algorithms, digital filtering, and PID computations without consuming multiple instruction cycles.
