Product details
Overview
HD64F38024RWV from Renesas Electronics is an 8-bit single-chip microcontroller in the H8/300L Super Low Power Series, featuring a 16 MHz H8/300L CPU core, 32 KB on-chip Flash ROM, 1 KB RAM, and integrated peripherals including 10-bit × 8-channel ADC, SCI, 10-bit PWM, LCD controller (32 seg × 4 com), and four 16-bit timers - used in industrial control panels requiring compact, low-power embedded logic with display and analog sensing.
For engineers reviewing the HD64F38024RWV datasheet, HD64F38024RWV pinout, HD64F38024RWV application, or HD64F38024RWV equivalent, key selection criteria include Flash memory size, operating voltage range (2.7–5.5 V), LCD driver capability, and TFP-80C package compatibility for space-constrained board layouts.
Technical Context
The HD64F38024RWV implements the H8/300L CPU architecture with Harvard-style memory mapping, supporting 16-bit address/data bus operation and 24-bit linear addressing via bank switching. It integrates a programmable on-chip oscillator, power-on reset (POR), and low-voltage detection (LVD) circuit for robust startup and brown-out protection.
Peripheral subsystems include a UART/Synchronous SCI interface with selectable clock sources, a 10-bit successive-approximation ADC with sample-and-hold, and a dedicated LCD controller supporting static and multiplexed drive modes - all accessible via memory-mapped I/O registers and configurable through dedicated control bits in the system control module.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F38024R | Mask ROM (8–32 KB) instead of Flash; no in-field reprogramming capability; identical pinout and peripheral set. | Suitable only for high-volume, fixed-firmware products where cost-per-unit outweighs flexibility. | Select HD64F38024R only when firmware is finalized and production volume justifies mask ROM NRE savings. |
| HD64F38124 | Higher max frequency (20 MHz); adds POR circuit and LVD; same TFP-80C package and instruction set compatibility. | Better suited for time-critical control loops or higher-throughput SCI communication requiring >16 MHz timing margin. | Choose HD64F38124 if design requires guaranteed 20 MHz operation or enhanced reset reliability in wide-temperature environments. |
Compared with HD64F38024RWV, HD64F38024R sacrifices field-upgradability for lower unit cost, while HD64F38124 extends timing headroom and reset robustness - both retain identical peripheral integration and software compatibility, making them drop-in alternatives only where Flash programmability or 16 MHz ceiling are not critical.

The H8/300L CPU core executes most instructions in a single cycle at this rate, enabling deterministic real-time response in control applications. HD64F38024RWV performance remains stable across its full industrial temperature range (–40°C to +85°C).
Does the HD64F38024RWV support in-system programming (ISP)?
Yes, the HD64F38024RWV supports in-system programming via its on-chip Flash memory (F-ZTAT™). Firmware updates can be performed using the on-chip emulator (OCE) interface or through user-developed bootloader code executed from RAM. Programming requires no external hardware programmer - only a UART or SCI connection and appropriate host-side utility. HD64F38024RWV Flash endurance is rated for 10,000 write/erase cycles, ensuring field-upgrade reliability over product lifetime.
What LCD configurations does the HD64F38024RWV support?
The HD64F38024RWV integrates a dedicated LCD controller supporting up to 32 segments and 4 commons, enabling static, 1/2-duty, or 1/3-duty drive modes. It provides programmable bias voltage, frame frequency, and internal charge pump - allowing direct connection to common alphanumeric LCD modules without external drivers. HD64F38024RWV LCD outputs are mapped to dedicated SEG0–SEG31 and COM0–COM3 pins, electrically optimized for low-power, low-noise segment driving in battery-operated devices.
Is the HD64F38024RWV pin-compatible with other H8/38024 Group members?
Yes, the HD64F38024RWV shares identical pinout and package (TFP-80C) with all members of the H8/38024 Group, including HD64F38024R and HD64F38024S variants. Peripheral register maps, interrupt vectors, and memory layout are fully compatible across the group. This allows hardware reuse across firmware variants - for example, migrating from Flash-based HD64F38024RWV to mask-ROM HD64F38024R without PCB redesign. HD64F38024RWV pin assignments match Renesas Hardware Manual REJ09B0042-0800 Section 1.3.1.
What development tools are officially supported for the HD64F38024RWV?
Renesas officially supports the HD64F38024RWV with High-Performance Embedded Workshop (HEW), C/C++ Compiler for H8/300, and H8/300 Series Simulator/Debugger (REJ10B0211).
