Product details
Overview
M30879FKBGP#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, 768 KB + 4 KB data flash, 31 KB RAM, and no CAN module. It delivers 32 MHz operation at 4.2–5.5 V, supports 26-channel 10-bit ADC, dual 8-bit DACs, and integrated 3-phase motor control timers - deployed in office equipment and industrial automation systems.
For engineers reviewing the M30879FKBGP#U5 datasheet, M30879FKBGP#U5 pinout, M30879FKBGP#U5 application, or M30879FKBGP#U5 equivalent, key selection considerations include its 100-pin PLQP0100KB-A package, absence of CAN interfaces, single-chip mode operation with 16-Mbyte address space, and support for wait/stop low-power modes.
Technical Context
The M30879FKBGP#U5 implements the M32C/80 CPU core with 108 basic instructions and a 16×16→32-bit multiplier plus 16×16+48→48-bit multiply-add unit. Its clock system integrates main/sub oscillators, on-chip oscillator, and PLL frequency synthesizer with selectable division ratios (1–16), enabling precise timing control across variable supply conditions.
Peripheral integration includes DMAC (4 channels, cycle-steal), DMACII (burst/single/chain transfer), five 16-bit Timer A units (PWM, encoder input), six 16-bit Timer B units (pulse width/period measurement), and intelligent I/O with 10 waveform generation channels - all coordinated via 70 interrupt vectors and 7 priority levels.

FAQ
What is the maximum operating frequency and supply voltage range for the M30879FKBGP#U5?
The M30879FKBGP#U5 operates at up to 32 MHz with VCC1 between 4.2 V and 5.5 V, or at 24 MHz with VCC1 from 3.0 V to 5.5 V. VCC2 must be within 3.0 V to VCC1. These ranges are strictly defined in the REJ03B0127-0151 datasheet and must be observed to ensure reliable execution timing and flash programming integrity for the M30879FKBGP#U5.
Does the M30879FKBGP#U5 include CAN interface capability?
No, the M30879FKBGP#U5 belongs to the M32C/87B subfamily and explicitly excludes CAN modules. Tables 1.5–1.7 and footnote 5 in the REJ03B0127-0151 datasheet confirm that M32C/87B devices have zero CAN channels - unlike M32C/87 (2 channels) or M32C/87A (1 channel). CAN-related pins are unconnected in the M30879FKBGP#U5 silicon.
What package type and pin count does the M30879FKBGP#U5 use?
The M30879FKBGP#U5 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch), as confirmed in Table 1.7 and Figure 1.1 of the REJ03B0127-0151 datasheet. This is distinct from the 144-pin variant used by higher-memory M32C/87B parts like M3087BFKBGP.
How many analog-to-digital converter channels does the M30879FKBGP#U5 support?
The M30879FKBGP#U5 supports 26 channels of 10-bit ADC in single-chip mode, as specified in Table 1.4 of the REJ03B0127-0151 datasheet. This count reduces to 10 channels in memory expansion or microprocessor modes. All channels include sample-and-hold functionality, critical for accurate multi-sensor acquisition in the M30879FKBGP#U5.
What debug and programming features are available on the M30879FKBGP#U5?
The M30879FKBGP#U5 includes full on-chip debug support and on-board flash reprogramming capability, as documented in Section 1.1.2 and Table 1.4 of REJ03B0127-0151. These features enable in-system firmware updates, real-time breakpoint debugging, and ROM code protection via ID code check - essential for secure field maintenance of deployed M30879FKBGP#U5 units.
