Product details
Overview
M30626SPFP#U3C from Renesas Electronics is a ROM-less 16-bit microcontroller in the M16C/62P Group, built on the M16C/60 Series CPU core and packaged in a 100-pin plastic QFP (PRQP0100JB-A). It delivers 41.7 ns minimum instruction execution at 24 MHz, integrates 31 KB RAM, 2-channel DMAC, 10-bit A/D converter with 26 channels, and dual 8-bit D/A converters. It targets industrial control subsystems requiring flexible firmware loading and real-time peripheral management.
For engineers reviewing the M30626SPFP#U3C datasheet, M30626SPFP#U3C pinout, M30626SPFP#U3C application, or M30626SPFP#U3C equivalent, this page provides verified technical context, package mapping, functional specifications, and validated alternative options for embedded system design and BOM optimization.
Technical Context
The M30626SPFP#U3C implements a single-chip 16-bit CMOS microcomputer architecture with a fixed 1 MB address space and supports single-chip operating mode only. Its internal clock generation includes main/subclock circuits, on-chip oscillator, and PLL synthesizer - all equipped with built-in feedback resistors - enabling precise timing control without external components.
Peripheral integration includes five 16-bit Timer A channels, six 16-bit Timer B channels, three serial interfaces (UART + clock-synchronous + I²C + IEBus), CCITT-CRC calculation circuit, and watchdog timer with 15-bit counter and prescaler. The device supports wait and stop low-power modes, achieving 2.0 µA at 5 V in wait mode and 0.8 µA in stop mode.

FAQ
What is the operating voltage range for M30626SPFP#U3C?
M30626SPFP#U3C operates with VCC1 = VCC2 = 4.0–5.5 V at 24 MHz BCLK. Unlike other variants, it does not support 2.7–3.3 V operation. This fixed dual-supply requirement simplifies power design but mandates tight regulation across both rails. Always verify voltage stability under load using the recommended decoupling capacitors per the Renesas hardware manual.
Does M30626SPFP#U3C include on-chip Flash memory?
No, M30626SPFP#U3C is a ROM-less variant - it contains no embedded program memory. Firmware must be loaded externally via bootloader or debug interface. This distinguishes it from Flash versions like M30626FHPGP#U7. The "S" in the part number explicitly denotes ROM-less configuration per Renesas' naming convention.
Which serial interfaces are supported by M30626SPFP#U3C?
M30626SPFP#U3C supports three serial channels: one UART, one clock-synchronous interface, and one combined I²C/IEBus channel. The IEBus function is essential for legacy Japanese automotive networks, while I²C enables sensor and EEPROM interfacing. All channels are configurable via dedicated control registers and share port pins with GPIO functionality.
What is the maximum A/D conversion rate achievable with M30626SPFP#U3C?
M30626SPFP#U3C's 10-bit A/D converter achieves up to 100 kSPS when using internal sampling clock derived from BCLK. Conversion time is 10 µs per channel, and the 26-channel multiplexer allows rapid scanning across multiple sensors. For deterministic timing, use the A/D start trigger linked to Timer B overflow events.
Is M30626SPFP#U3C qualified for automotive applications?
M30626SPFP#U3C is rated for -40°C to +85°C ambient operation and supports IEBus - a standard in Japanese automotive body electronics. While not AEC-Q100 certified, its temperature grade and interface compliance make it suitable for non-safety-critical automotive modules such as door controllers and seat adjusters, provided system-level validation is performed.
