Renesas M30879FLBGP#U5

Overview

M30879FLBGP#U5 from Renesas Electronics is a 100-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, and no CAN module. It operates at up to 32 MHz (VCC1 = 4.2–5.5 V), supports 16-Mbyte external bus expansion, and integrates dual 8-bit D/A converters, 10-bit A/D with 26 channels (single-chip mode), and advanced timer subsystems for motor control - deployed in office equipment and industrial automation systems.

For engineers reviewing the M30879FLBGP#U5 datasheet, M30879FLBGP#U5 pinout, M30879FLBGP#U5 application, or M30879FLBGP#U5 equivalent, key selection considerations include its 100-pin PLQP0100KB-A package, absence of CAN interfaces, single-chip/microprocessor operating modes, 3-phase inverter control capability via Timer A/B, and support for I²C, UART (6 channels), and IrDA - all critical for deterministic real-time embedded control designs requiring flash reprogrammability and low-power stop mode (0.8 μA).

Technical Context

The M30879FLBGP#U5 implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit, 16×16+48→48-bit), enabling efficient signal processing and motor algorithm execution. Its memory architecture includes on-chip 512 KB main flash plus 4 KB dedicated data flash, 31 KB RAM, and configurable external bus interface supporting 8-/16-bit data width, 1–7 wait states, and four chip selects.

Peripheral integration centers on deterministic timing: five 16-bit Timer A units (PWM, encoder input, one-shot) and six 16-bit Timer B units (pulse width/period measurement), coordinated for 3-phase motor control using A1/A2/A4/B2. Dual DMAC engines (DMAC and DMACII) provide flexible data movement triggered by 43 sources, supporting burst, chain, and calculation transfers - essential for high-throughput sensor acquisition and communication buffering.

FAQ

What is the maximum operating frequency and voltage range for the M30879FLBGP#U5?

The M30879FLBGP#U5 operates at up to 32 MHz when VCC1 is 4.2–5.5 V, and at 24 MHz across VCC1 = 3.0–5.5 V. VCC2 must be 3.0 V to VCC1. These ranges are defined in the official Renesas specification document REJ03B0127-0151 Rev.1.51, ensuring reliable timing margin and flash programming stability under industrial supply conditions. The M30879FLBGP#U5 does not support operation outside these validated voltage/frequency combinations.

Does the M30879FLBGP#U5 include CAN interface functionality?

No, the M30879FLBGP#U5 belongs to the M32C/87B subgroup and explicitly excludes CAN modules per Renesas documentation (Table 1.7 and Note 5 in Figure 1.2). Pins labeled CAN0IN/CAN0OUT and CAN1IN/CAN1OUT are present but non-functional in this variant. The M30879FLBGP#U5 is intended for applications where CAN is unnecessary - such as standalone motor drives or sensor concentrators using UART/I²C instead.

What package type and pin count does the M30879FLBGP#U5 use?

The M30879FLBGP#U5 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch), as confirmed in Table 1.4 and Figure 1.5 of the Renesas datasheet REJ03B0127-0151. This differs from the 144-pin variant used by M32C/87 and M32C/87A models. The M30879FLBGP#U5 shares this exact package with other M32C/87B members like M30876FJBGP and M30875FHBGP.

How many A/D converter channels are available on the M30879FLBGP#U5?

In single-chip mode, the M30879FLBGP#U5 provides 26 channels of 10-bit A/D conversion with sample-and-hold, as specified in Table 1.4. In memory expansion or microprocessor mode, this reduces to 10 channels. This matches the 100-pin package limitation noted in Figure 1.2 (Note 2), and is fewer than the 34-channel capability of the 144-pin M32C/87 variants. The M30879FLBGP#U5's A/D subsystem supports simultaneous sampling only via external hardware - internal sequencing is sequential.

What debug and programming capabilities does the M30879FLBGP#U5 support?

The M30879FLBGP#U5 supports on-chip debug (OCD) via the standard Renesas E8/E8a emulator interface and in-system flash reprogramming using the on-chip bootloader. These features are documented in Section 1.1.2 and Table 1.4 of REJ03B0127-0151. No external programming hardware is required for firmware updates - the M30879FLBGP#U5 can be reprogrammed in-circuit via UART or dedicated debug pins, preserving full flash security (ROM code protect and ID code check).
