Product details
Overview
M30879FKBGP#U3 from Renesas Electronics is a 100-pin LQFP microcontroller in the M32C/87B Group, featuring the M32C/80 CPU core, 768 KB flash + 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 converter with 26 channels, and five UART interfaces - deployed in industrial motor control and office automation systems.
For engineers reviewing the M30879FKBGP#U3 datasheet, M30879FKBGP#U3 pinout, M30879FKBGP#U3 application, or M30879FKBGP#U3 equivalent, key selection considerations include its 100-pin LQFP package (PLQP0100KB-A), absence of CAN peripherals, single-chip/microprocessor operating modes, and support for I²C, IrDA, and HDLC serial protocols in embedded real-time control designs.
Technical Context
The M30879FKBGP#U3 implements the M32C/80 16-bit CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit). Its clock system includes main/sub oscillators, on-chip oscillator, and PLL frequency synthesizer with selectable division ratios (1–16), enabling precise timing for multi-mode operation including wait and stop low-power states.
Peripheral integration includes DMAC (4-channel cycle-steal) and DMACII (burst/single/chain transfer), Timer A (5×16-bit) with PWM and 2-phase encoder input, Timer B (6×16-bit) with pulse width/period measurement, and intelligent I/O supporting input capture (8 channels), output compare (10 channels), and HDLC/IEBus communication - all mapped to dedicated pins in the 100-pin LQFP footprint.

FAQ
Does M30879FKBGP#U3 support CAN communication?
No, M30879FKBGP#U3 is an M32C/87B variant and explicitly excludes CAN modules per Renesas documentation. The "B" suffix denotes zero CAN channels, unlike M32C/87 (2 channels) or M32C/87A (1 channel). All CAN-related pins (e.g., CAN0IN, CAN0OUT) are non-functional in M30879FKBGP#U3 and must be left unconnected or used as general-purpose I/O if configured appropriately.
What is the maximum A/D conversion rate supported by M30879FKBGP#U3?
M30879FKBGP#U3 supports up to 26 input channels in single-chip mode with 10-bit resolution, but the datasheet does not specify a maximum sample rate. Conversion time depends on clock source and prescaler settings; typical acquisition uses internal ADC clock derived from CPU clock divided by programmable ratio, with sample-and-hold enabled. For deterministic timing, use the A/D trigger from Timer A or external event.
Can M30879FKBGP#U3 operate at 3.3 V supply voltage?
Yes, M30879FKBGP#U3 supports VCC1 = 3.0–5.5 V. At 24 MHz operation, it functions reliably at VCC1 = VCC2 = 3.3 V, drawing 23 mA active current and dropping to 45 μA in wait mode. The device's dual-supply architecture (VCC1 for core/I/O, VCC2 for analog/external bus) allows mixed-voltage system design when interfacing with 3.3 V peripherals.
Is the PLQP0100KB-A package RoHS compliant?
Yes, M30879FKBGP#U3 in PLQP0100KB-A package complies with EU RoHS Directive requirements. Renesas confirms environmental compliance for this product family in official documentation, and Aetrix Electronics sources only RoHS-compliant lots with full material declarations available upon request for industrial and medical-grade programs.
What debug interfaces are available on M30879FKBGP#U3?
M30879FKBGP#U3 supports on-chip debug via dedicated debug port (not SWD or JTAG) using Renesas E8/E8a emulators. It enables full breakpoint control, register/memory inspection, and flash programming through the on-chip debug module - no external debug header required. Debug functionality remains active even with ROM code protection enabled, provided correct ID code authentication is performed.
