Overview
M38039GCHHP#U0 from Renesas Electronics is an 8-bit CMOS microcontroller based on the 740 family core, featuring 48 KB QzROM, 2048 bytes RAM, 10-bit 16-channel A/D converter, dual 8-bit D/A converters, and integrated LED drive capability for up to 8 segments. It operates across 1.8–5.5 V with selectable clock modes (high/middle/low-speed) and targets embedded control in household appliances and office automation equipment.
For engineers reviewing the M38039GCHHP#U0 datasheet, M38039GCHHP#U0 pinout, M38039GCHHP#U0 application, or M38039GCHHP#U0 equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options for design-in decisions.
Technical Context
The M38039GCHHP#U0 implements a single-chip 8-bit architecture with dual clock generating circuits supporting external ceramic resonators or quartz crystals (XIN/XOUT and XCIN/XCOUT), enabling flexible low-power operation down to 32 kHz. Its CPU executes 71 basic instructions with minimum 0.24 µs instruction time at 16.8 MHz.
It integrates analog peripherals including a 10-bit A/D converter with 16 input channels (AN0–AN15), two independent 8-bit D/A converters (DA1/DA2), and an 8-bit PWM channel with 8-bit prescaler - all sharing common reference (VREF) and analog ground (AVSS) pins for precision signal conditioning.

FAQ
What is the maximum oscillation frequency supported by the M38039GCHHP#U0?
The M38039GCHHP#U0 supports a maximum oscillation frequency of 16.8 MHz in high-speed mode using the main clock circuit (XIN/XOUT). At this frequency, the minimum instruction execution time is 0.24 µs. The sub-clock circuit supports up to 32 kHz for low-power timing functions.
Does the M38039GCHHP#U0 include on-chip D/A converters, and what are their specifications?
Yes, the M38039GCHHP#U0 includes two independent 8-bit D/A converters (DA1 on P30, DA2 on P31). Both are referenced to the VREF pin and support voltage output ranges determined by the applied reference voltage (1.0–5.0 V). They operate in parallel with the A/D subsystem and share the same AVSS ground.
What package type does the M38039GCHHP#U0 use, and how many pins does it have?
The M38039GCHHP#U0 uses the PLQP0064KB-A package: a 64-pin, 10 × 10 mm LQFP with 0.5 mm pitch. This matches the pinout shown in Figure 1 of the REJ03B0166-0113 datasheet and is distinct from the SDIP (SP) and larger LQFP (KP) variants in the same family.
Can the M38039GCHHP#U0 drive LEDs directly, and what are the current limits?
Yes, the M38039GCHHP#U0 features eight dedicated LED drive pins (P20–P27) capable of sourcing or sinking up to 10 mA average current per pin (20 mA peak), with a total device limit of 80 mA. These pins are optimized for direct connection to common-anode or common-cathode 7-segment displays without external transistors.
What is the A/D converter resolution and channel count on the M38039GCHHP#U0?
The M38039GCHHP#U0 integrates a single 10-bit successive-approximation A/D converter with 16 input channels (AN0–AN15), mapped across ports P0, P6, and P3. It supports both 10-bit and 8-bit readout modes - the latter enabling faster sampling at reduced resolution for time-critical applications.
