Product details
Overview
HD64738024DV from Renesas Technology Corp. is an 8-bit single-chip microcontroller in the H8/38024 Series, featuring an H8/300L CPU core, on-chip 64 KB PROM (ZTAT™), 10-bit A/D converter, LCD controller/driver, six timers, and dual-channel 10-bit PWM - designed for embedded systems requiring integrated display control and mixed-signal processing in industrial instrumentation and consumer appliances.
For engineers reviewing the HD64738024DV datasheet, HD64738024DV pinout, HD64738024DV application, or HD64738024DV equivalent, key selection considerations include its ZTAT™ PROM programmability, LCD driver capability with segment/common drive support, 10-bit ADC resolution with 8 input channels, and compatibility with the E10T on-chip emulator for debug during early firmware development.
Technical Context
The HD64738024DV implements the H8/300L CPU instruction set (backward-compatible with H8/300), operates at up to 16 MHz system clock frequency, and integrates a dedicated LCD controller supporting up to 40 segments × 8 commons. Its memory map includes 64 KB on-chip PROM, 2 KB RAM, and peripheral register space mapped to fixed addresses.
Power management includes five low-power modes (Sleep, Standby, Watch, Subsleep, Subactive) controlled via system control registers, with oscillator stabilization timing specified for subclock (32.768 kHz) and main clock (1–16 MHz) domains. The device supports serial communication via a UART-compatible SCI interface and features programmable port I/O with configurable pull-up resistors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F38024FV | Flash memory (F-ZTAT™) instead of PROM; supports in-system reprogramming without UV exposure or socket removal. | Better suited for designs requiring frequent firmware updates or field calibration; lacks UV-erasable PROM's long-term data retention guarantee. | Select HD64F38024FV when iterative firmware development or post-deployment updates are required; HD64738024DV remains optimal for fixed-function, high-reliability production units. |
| HD64338024FV | Mask ROM version - lower unit cost but no field-programmability; identical peripheral set and pinout. | Appropriate only for mature, volume-production designs where firmware is finalized and unchanging across product lifetime. | Choose HD64338024FV for cost-sensitive, high-volume applications with locked firmware; HD64738024DV provides flexibility for pre-production validation and small-batch customization. |
Compared with HD64F38024FV and HD64338024FV, the HD64738024DV offers the unique balance of one-time programmability with ZTAT™ speed and PROM-level data retention - making it optimal for applications needing assured firmware immutability after final calibration without sacrificing initial development agility.

FAQ
What is the maximum operating frequency of the HD64738024DV?
The HD64738024DV supports a maximum system clock frequency of 16 MHz using an external crystal or clock source. Its H8/300L CPU core executes instructions at this rate with cycle-accurate timing, and all on-chip peripherals - including the LCD controller and 10-bit ADC - are fully synchronized to this clock domain without additional gating or scaling constraints.
Does the HD64738024DV include an integrated LCD driver?
Yes, the HD64738024DV integrates a full-featured LCD controller/driver supporting static and multiplexed displays up to 40 segments × 8 commons. It provides programmable bias voltage generation, frame frequency control, and direct segment/common output drive capability - eliminating the need for external LCD driver ICs in most display-integrated applications.
What type of memory does the HD64738024DV use for program storage?
The HD64738024DV uses 64 KB of on-chip PROM implemented as ZTAT™ (Zero Turnaround Time) technology. This one-time programmable memory allows fast, reliable firmware loading without UV erasure or special programming voltages - ideal for production calibration and fixed-function deployment where firmware immutability is required after programming.
Can the HD64738024DV be debugged using the E10T on-chip emulator?
Yes, the HD64738024DV supports the E10T on-chip emulator via dedicated pins (P95, P33–P35). When enabled, these pins are reserved for debug signaling and cannot be used for general I/O. The emulator provides real-time trace, breakpoint, and memory inspection capabilities without requiring external JTAG hardware - accelerating firmware validation during development of HD64738024DV-based systems.
What power management features does the HD64738024DV support?
The HD64738024DV implements five distinct low-power modes: Sleep, Standby, Watch, Subsleep, and Subactive. Each mode offers different trade-offs between wake latency (as low as 2 µs in Subactive mode) and current consumption (down to 1 µA in Subsleep mode), enabling precise energy optimization for battery-powered or thermally constrained applications built around the HD64738024DV.
