Overview
M38K09F8LFP#U0 from Renesas Electronics is an 8-bit CMOS microcontroller based on the 740 family core, featuring 32 KB flash memory, 2048 bytes RAM, full-speed USB 2.0 interface (4 endpoints), 8-channel 10-bit A/D converter, and three 8-bit timers. It operates from 3.0–5.25 V across –20 to +85°C and targets PC peripheral I/O devices requiring integrated analog, serial, and USB connectivity.
For engineers reviewing the M38K09F8LFP#U0 datasheet, M38K09F8LFP#U0 pinout, M38K09F8LFP#U0 application, or M38K09F8LFP#U0 equivalent, this device serves as a single-chip solution for embedded USB peripherals with mixed-signal control, real-time timing, and low-voltage operation in space-constrained LQFP-64 designs.
Technical Context
The M38K09F8LFP#U0 implements the standard 740-family instruction set with 71 base instructions, minimum 0.25 µs instruction cycle at 8 MHz system clock, and supports both mask ROM and flash memory variants. Its CPU includes accumulator, dual index registers (X/Y), 8-bit stack pointer, and 16-bit program counter with zero-page and special-page addressing modes.
It integrates a programmable clock generating circuit supporting external ceramic resonator or quartz crystal (XIN/XOUT), USB transceiver with internal 3.3 V reference generation (enabled at VCC ≥ 4.0 V), and dedicated LED drive ports (P60–P63) capable of direct high-current output without external drivers.

FAQ
What is the maximum system clock frequency supported by the M38K09F8LFP#U0?
The M38K09F8LFP#U0 supports up to 12 MHz system clock frequency when using external crystal or resonator. At 12 MHz with 2-divide mode (φ = 6 MHz), it operates within 4.00–5.25 V; at 8 MHz through mode (φ = 8 MHz), same voltage range applies. The minimum instruction execution time is 0.25 µs at 8 MHz.
Does the M38K09F8LFP#U0 include an internal USB voltage reference?
Yes, the M38K09F8LFP#U0 includes an internal USB reference voltage circuit active when VCC is between 4.00 V and 5.25 V. For VCC between 3.60 V and 4.00 V, an external 3.3 V supply must be applied to USBVREF; below 3.60 V, USBVREF must be tied to VCC.
How many A/D input channels does the M38K09F8LFP#U0 support, and what is their resolution?
The M38K09F8LFP#U0 supports eight A/D input channels (AN0–AN7) with 10-bit resolution. It also allows 8-bit reading mode for faster conversion cycles, and shares these pins with port P1 (P10–P17), enabling flexible pin multiplexing.
Can the M38K09F8LFP#U0 drive LEDs directly without external current-limiting resistors?
Yes, the M38K09F8LFP#U0 provides four dedicated LED drive ports (P60–P63) with enhanced output current capability, allowing direct connection of standard LEDs without external series resistors - simplifying board layout and reducing component count.
What package type is used for the M38K09F8LFP#U0, and what are its dimensions?
The M38K09F8LFP#U0 uses the PLQP0064GA-A package: a 64-pin plastic LQFP with 14 mm × 14 mm body size and 0.8 mm lead pitch. This package is RoHS-compliant and optimized for surface-mount assembly in industrial and peripheral applications.
