Overview
D12324SVF25V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2324S group, featuring an H8S/2000 CPU core, 256 KB on-chip F-ZTAT™ flash memory, 16 KB RAM, and integrated peripherals including TPU, SCI, A/D converter, D/A converter, DMA controller, and watchdog timer. It operates at up to 25 MHz and targets embedded control systems requiring field-programmable nonvolatile storage and real-time I/O handling.
For engineers reviewing the D12324SVF25V datasheet, D12324SVF25V pinout, D12324SVF25V application, or D12324SVF25V equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options for industrial motor control, HVAC system management, programmable logic controllers, and factory automation edge nodes.
Technical Context
The D12324SVF25V implements the H8S/2000 32-bit internal architecture with 16-bit external data bus, supporting multiple operating modes (Mode 2–Mode 7) selected via MD0–MD2 pins. It integrates a 16-bit Timer Pulse Unit (TPU) with 8 channels, asynchronous serial communication interface (SCI) with baud rate generation up to 38.4 kbps at 25 MHz, and a 10-bit A/D converter with 8 input channels.
Flash memory supports ≥100 rewrite cycles with 10 ms/128-byte programming time and 50 ms/block erase time; data retention is guaranteed for 10 years. The device uses either TFP-120 (120-pin thin fine-pitch QFP) or FP-128B (128-pin plastic QFP) packages, both RoHS-compliant and rated for industrial temperature range (–40°C to +85°C).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2329B | Same H8S/2329 group; 512 KB flash, 32 KB RAM, identical peripheral set but higher memory density - no change in pinout or clock architecture. | Preferred where larger firmware image size or extended data logging capacity is required; otherwise functionally interchangeable in existing designs. | Select HD64F2329B when >256 KB code space or >16 KB RAM is needed; D12324SVF25V remains optimal for cost-sensitive, memory-constrained control nodes. |
| H8S/2328 | Pin-compatible variant with 384 KB flash and 24 KB RAM; shares same TFP-120/FP-128B packages and register map - differs only in memory sizing and minor feature enablement. | Suitable for migration paths requiring incremental memory growth without layout revision; supports identical peripheral initialization sequences. | Choose H8S/2328 for future-proofing where firmware expansion headroom is anticipated; D12324SVF25V offers best value for fixed-feature, volume-manufactured systems. |
Compared with HD64F2329B and H8S/2328, the D12324SVF25V delivers the optimal balance of flash/RAM capacity, peripheral integration, and industrial temperature support in a mature, widely deployed 16-bit platform - making it ideal for cost-conscious, high-reliability embedded control where memory requirements are stable and well-defined.

FAQ
What is the maximum operating frequency of the D12324SVF25V?
The D12324SVF25V operates at a maximum clock frequency of 25 MHz. This rating is specified under industrial temperature conditions (–40°C to +85°C) and with proper decoupling and power supply stability. The internal H8S/2000 CPU core sustains full instruction throughput and peripheral timing compliance at this frequency, enabling deterministic real-time control loop execution in applications such as motor drive and sensor processing. D12324SVF25V maintains timing integrity across its entire supported voltage range (typically 4.5 V to 5.5 V).
Does the D12324SVF25V include on-chip flash memory, and what are its endurance specifications?
Yes, the D12324SVF25V integrates 256 KB of F-ZTAT™ flash memory. Its endurance is rated for a minimum of 100 write/erase cycles per block, with typical erase time of 50 ms per block and programming time of 10 ms per 128-byte sector. Data retention is guaranteed for 10 years under normal operating conditions. These characteristics are confirmed in Renesas' Hardware Manual Rev.6.00 (REJ09B0220-0600), Section 22.2.6. D12324SVF25V supports in-system programming without external hardware programmers.
Which package types are available for the D12324SVF25V?
The D12324SVF25V is offered in two RoHS-compliant surface-mount packages: TFP-120 (120-pin thin fine-pitch QFP) and FP-128B (128-pin plastic QFP). Both packages support industrial temperature operation (–40°C to +85°C) and are compatible with standard reflow soldering profiles. Pin functions and electrical characteristics are identical across both variants; selection depends on board layout constraints and thermal requirements. D12324SVF25V documentation confirms full pin compatibility between these packages.
What peripheral modules are integrated into the D12324SVF25V?
The D12324SVF25V integrates a 16-bit Timer Pulse Unit (TPU) with 8 channels, a 10-bit A/D converter with 8 input channels, an 8-bit D/A converter, a serial communication interface (SCI), a 4-channel DMA controller, a watchdog timer (WDT), and a data transfer controller (DTC). These peripherals are fully documented in the H8S/2329 Group Hardware Manual and operate synchronously with the 25 MHz system clock. D12324SVF25V uses these modules to deliver self-contained control functionality without requiring external support ICs in many embedded applications.
Is the D12324SVF25V suitable for automotive applications?
No, the D12324SVF25V is classified as a "Standard" quality grade device per Renesas' product categorization and is intended for industrial, office, and consumer applications - not automotive or safety-critical systems. It is not qualified to AEC-Q100, lacks automotive-grade temperature screening (–40°C to +125°C), and does not include features such as enhanced ESD protection or fault injection test coverage required for automotive ECUs. D12324SVF25V should not be used in vehicle subsystems where failure could impact safety or regulatory compliance.
