Renesas M30879FLBGP#U3

Overview

M30879FLBGP#U3 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 ROM, 31 KB RAM, dual 10-bit ADC (26 channels), dual 8-bit DAC, and no CAN module. It operates at up to 32 MHz (VCC1 = 4.2–5.5 V) and targets industrial motor control and office automation systems requiring deterministic real-time I/O and low-power operation.

For engineers reviewing the M30879FLBGP#U3 datasheet, M30879FLBGP#U3 pinout, M30879FLBGP#U3 application, or M30879FLBGP#U3 equivalent, key selection criteria include its 100-pin LQFP package (PLQP0100KB-A), absence of CAN interfaces, 26-channel ADC in single-chip mode, integrated 3-phase motor control timers (using TA1–TA4 and TB2), and support for wait/stop low-power modes with sub-1 μA stop current.

Technical Context

The M30879FLBGP#U3 implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit), enabling efficient signal processing in motor and power control loops. Its external bus interface supports 16-Mbyte address space with configurable 1–7 wait states, 4 chip selects, and switchable 8-/16-bit data bus width - critical for interfacing with external memory or peripherals in embedded industrial controllers.

It integrates two independent DMAC units: DMAC (4 channels, cycle-steal, 43 trigger sources) and DMACII (burst/single transfer, chain/calculation functions), allowing concurrent high-bandwidth data movement without CPU intervention. Peripheral timing is managed by five 16-bit Timer A units (PWM, encoder input, one-shot) and six 16-bit Timer B units (pulse width/period measurement), coordinated for precise 3-phase inverter gate drive with on-chip dead-time insertion.

FAQ

What is the maximum operating frequency and supply voltage range for the M30879FLBGP#U3?

The M30879FLBGP#U3 operates at up to 32 MHz with VCC1 between 4.2 V and 5.5 V, or at 24 MHz with VCC1 between 3.0 V and 5.5 V. VCC2 must be maintained between 3.0 V and VCC1. These ranges ensure reliable operation across industrial power rail variations while maintaining timing accuracy for real-time control tasks executed by the M30879FLBGP#U3.

Does the M30879FLBGP#U3 include CAN interface capability?

No, the M30879FLBGP#U3 belongs to the M32C/87B subgroup and explicitly excludes CAN modules. Unlike M32C/87 (dual CAN) or M32C/87A (single CAN), this variant omits all CAN0/CAN1 pins and associated peripheral logic. Engineers selecting the M30879FLBGP#U3 must implement alternative communication (e.g., UART, I²C, or external CAN controller) if networked control is required.

How many analog-to-digital converter channels does the M30879FLBGP#U3 support in single-chip mode?

In single-chip mode, the M30879FLBGP#U3 supports 26 channels of 10-bit ADC conversion. This count is confirmed in Table 1.4 for the 100-pin package and applies specifically to the M32C/87B variant. The M30879FLBGP#U3 uses these channels for simultaneous voltage/current sensing in motor control or multi-sensor monitoring in industrial equipment.

What package type and pin count does the M30879FLBGP#U3 use?

The M30879FLBGP#U3 uses a 100-pin LQFP package designated PLQP0100KB-A, measuring 14 mm × 14 mm with 0.5 mm lead pitch. This package is distinct from the 144-pin variant used by other M32C/87 family members and is verified in Table 1.7 and Figure 1.1 of the official Renesas documentation for the M30879FLBGP#U3.

What low-power modes are supported by the M30879FLBGP#U3, and what are their typical current draws?

The M30879FLBGP#U3 supports wait mode (~45 μA at ~1 MHz, VCC1 = VCC2 = 3.3 V) and stop mode (0.8 μA, VCC1 = VCC2 = 3.3 V). These modes are enabled via software-controlled register settings and allow rapid wake-up via external interrupt or internal timer event - essential for battery-backed industrial sensors or energy-conscious office equipment using the M30879FLBGP#U3.
