Product details
Overview
M38039FFLKP#Y1 from Renesas Electronics is a Flash-memory-based 8-bit CMOS microcomputer in the 3803 (Spec.L) group, built on the 740 family core. It integrates 60 KB Flash ROM, 2048 bytes RAM, 10-bit × 16-channel A/D converter, dual 8-bit D/A converters, 8-bit × 4 + 16-bit timers, UART/Clock-sync serial interfaces, and LED-direct-drive I/O (8 pins, 15 mA avg). It targets embedded control in household appliances and office automation systems requiring analog signal acquisition and low-power operation.
For engineers reviewing the M38039FFLKP#Y1 datasheet, M38039FFLKP#Y1 pinout, M38039FFLKP#Y1 application, or M38039FFLKP#Y1 equivalent, this page delivers verified technical context, package-specific pin mapping for PLQP0064GA-A (64-pin LQFP), real-world use scenarios, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The M38039FFLKP#Y1 implements the standard 740-family instruction set (71 basic instructions) with 0.24 µs minimum instruction execution time at 16.8 MHz. Its dual clock-generating circuits support external ceramic resonators or quartz crystals for main/sub-clock domains, enabling flexible timing architecture across high-, middle-, and low-speed operating modes.
It features three independent serial I/O modules (SI/O1–SI/O3), each configurable as UART or clock-synchronized interface, plus dedicated PWM output (P56), watchdog timer (16-bit), and hardware interrupt support across 21 sources (16 vectors). Analog subsystem includes shared VREF/AVSS rails, 16-channel A/D with 8-bit read capability, and two independent 8-bit D/A channels.

FAQ
What is the maximum operating frequency of the M38039FFLKP#Y1?
The M38039FFLKP#Y1 supports a maximum oscillation frequency of 16.8 MHz in high-speed mode. At this frequency, the minimum instruction execution time is 0.24 µs. The device also supports lower-frequency operation down to 32 kHz for ultra-low-power applications, with corresponding voltage ranges specified per mode in the datasheet.
Does the M38039FFLKP#Y1 support in-system programming?
Yes, the M38039FFLKP#Y1 supports in-system programming via software commands. It uses block-erase and byte-programming methods with VCC = 2.7–5.5 V as both supply and programming voltage. The Flash memory is rated for 100 program/erase cycles, making it suitable for field firmware updates in appliance and industrial control applications.
What are the key differences between the KP and HP package variants of the M38039FFLKP#Y1?
The M38039FFLKP#Y1 uses the PLQP0064GA-A (64-pin, 14 × 14 mm, 0.8 mm pitch) LQFP package, while the HP variant (M38039FFLHP#Y1) uses PLQP0064KB-A (64-pin, 10 × 10 mm, 0.5 mm pitch). Both share identical silicon, peripherals, and pin functions, but differ in mechanical dimensions and pitch - requiring separate PCB footprints and layout validation.
Can the M38039FFLKP#Y1 operate from a 3.3 V supply?
Yes, the M38039FFLKP#Y1 operates from 2.7 V to 5.5 V in Flash memory mode. At 3.3 V, it supports up to 12.5 MHz in high-speed mode and 8.4 MHz in middle-speed mode. This makes it compatible with standard 3.3 V logic systems without level-shifting, provided clock source and peripheral timing constraints are met.
How many analog input channels does the M38039FFLKP#Y1 support?
The M38039FFLKP#Y1 supports 16 analog input channels (AN0–AN15) mapped to P00–P07 and P60–P67. Its 10-bit A/D converter provides selectable 8-bit or 10-bit read modes, enabling faster sampling when full resolution is not required - useful in real-time control loops with tight timing budgets.
