Product details
Overview
HD64F38024RLPV from Renesas Electronics is an 8-bit single-chip microcontroller in the H8/38024R Group, built on the H8/300L CPU core and integrating 32 KB flash ROM, 1 KB RAM, 10-bit A/D converter (8 channels), LCD controller/driver (32 seg × 4 com), and multiple timers including WDT, UART/Synchronous SCI, and 10-bit PWM. It operates at up to 16 MHz within 4.5–5.5 V and targets embedded control in industrial and consumer instrumentation.
For engineers reviewing the HD64F38024RLPV datasheet, HD64F38024RLPV pinout, HD64F38024RLPV application, or HD64F38024RLPV equivalent, key selection criteria include its FP-80A package, flash-based reprogrammability, integrated LCD driver for low-power display interfaces, and support for 13 internal-wakeup external interrupts - all critical for cost-sensitive, space-constrained control systems requiring field firmware updates.
Technical Context
The HD64F38024RLPV implements the H8/300L 8-bit CISC CPU with 16-MHz maximum operation, 24-bit address space, and Harvard-style memory architecture separating program and data paths. Its on-chip peripheral set includes a 10-bit successive-approximation ADC with sample-and-hold, four independent timer modules (A/C/F/G), and a dedicated LCD controller supporting static and 1/2–1/4 duty drive modes.
It supports three power supply configurations: standard 4.5–5.5 V operation, low-voltage detection (LVD), and power-on reset (POR) - all implemented in hardware without external components. The device uses flash memory (F-ZTAT™) for nonvolatile program storage, enabling in-system programming via on-chip serial interface and full erase/write cycle endurance of ≥10,000 cycles.

FAQ
What is the maximum operating frequency of the HD64F38024RLPV?
The HD64F38024RLPV supports a maximum operating frequency of 16 MHz when powered at 4.5–5.5 V. This frequency is achieved using the internal high-speed oscillator or an external crystal/resonator connected to OSC1/OSC2 pins. Operation above 16 MHz is not supported and may cause undefined behavior or timing violations in on-chip peripherals such as the A/D converter or SCI module.
Does the HD64F38024RLPV include power-on reset (POR) and low-voltage detection (LVD) circuitry?
No, the HD64F38024RLPV does not integrate POR or LVD functions. These features are present in the H8/38124 Group (e.g., HD64F38124RLPV) but omitted from the H8/38024R Group. For reliable startup and brown-out protection, external reset ICs such as the uP reset supervisor R3111 series must be used with HD64F38024RLPV in production designs.

The HD64F38024RLPV provides 51 general-purpose I/O pins across eight ports (P0–P7), plus 9 input-only and 6 output-only pins - totaling 66 usable signal terminals. All I/O pins are CMOS-compatible, support TTL-level inputs, and can be individually configured as input, output, or alternate function (e.g., SCI TX/RX, PWM output, timer capture) via port control registers in the H8/300L architecture.
Can the HD64F38024RLPV drive an LCD display directly without external components?
Yes, the HD64F38024RLPV integrates a full LCD controller/driver supporting up to 32 segments and 4 commons (128 segments total). It provides built-in bias generation and segment/common drive capability (±3 mA), enabling direct connection to static or 1/2–1/4 duty LCD glass without external drivers, charge pumps, or resistor networks - confirmed in Renesas Hardware Manual REJ09B0042-0800, Section 6.12.
What development tools are officially supported for programming the HD64F38024RLPV flash memory?
Renesas officially supports programming the HD64F38024RLPV flash memory using the E8 emulator with High-Performance Embedded Workshop (Hew) IDE, or the standalone Flash Development Toolkit (FDT) with compatible debug adapters. In-system programming is also possible via the on-chip serial interface (SCI) using custom host software - detailed in Application Note REJ05B0464 and the H8/300L Series Software Manual REJ09B0214.
