Overview
DF2329BVF25V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2329 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 and D/A converters, WDT, and DMAC. 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 DF2329BVF25V datasheet, DF2329BVF25V pinout, DF2329BVF25V application, or DF2329BVF25V equivalent, this page delivers verified technical context, package mapping, functional pin roles, key timing and memory parameters, and validated alternative options for industrial control, motor drive, and instrumentation designs.
Technical Context
The DF2329BVF25V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting ROM-enabled and ROM-disabled expansion modes via MD0–MD2 pins. It integrates a 16-bit Timer Pulse Unit (TPU) with 8 channels, dual serial communication interfaces (SCI), and a 10-bit A/D converter with 16 input channels.
Its flash memory supports ≥100 rewrite cycles with 10 ms/128-byte programming time and 50 ms/block erase time; the on-chip bus controller enables configurable chip select signals (CS0–CS7) and wait-state control for external memory interfacing at up to 25 MHz system clock.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2328B | 256 KB flash, 16 KB RAM, identical pinout in FP-128B, but lacks D/A converter and has only one SCI module. | Suitable for cost-sensitive motor control where DAC is unused and single serial port suffices. | Select HD64F2328B when DAC and second SCI are unnecessary and BOM cost reduction is prioritized. |
| HD64F2326 | 128 KB flash, 8 KB RAM, same peripheral set including DAC and dual SCI, but rated for 20 MHz max frequency. | Better suited for lower-clock, lower-power applications where 25 MHz timing margin is not required. | Choose HD64F2326 for battery-powered or thermally constrained designs needing identical feature set at reduced speed grade. |
Compared with DF2329BVF25V, HD64F2328B omits the DAC and second SCI-reducing analog control flexibility-while HD64F2326 retains full peripheral compatibility but trades 25 MHz performance for lower power and cost at 20 MHz, making it ideal for thermally sensitive deployments.

FAQ
What is the maximum operating frequency of the DF2329BVF25V?
The DF2329BVF25V supports a maximum operating frequency of 25 MHz. This clock speed applies to both the CPU core and synchronized peripherals such as the TPU and SCI modules. The device accepts an external clock or crystal source within 1–25 MHz range, and timing specifications-including A/D conversion time and bus access latency-are guaranteed up to this frequency under specified VCC and temperature conditions. DF2329BVF25V must be operated within its rated voltage (5 V ±10%) and ambient temperature range (–20°C to +75°C) to maintain 25 MHz functionality.
Does the DF2329BVF25V include on-chip flash memory, and what are its endurance characteristics?
Yes, the DF2329BVF25V integrates 256 KB of F-ZTAT™ flash memory. Its endurance is rated for a minimum of 100 rewrite cycles, 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 REJ09B0220-0600, Section 22.2.6. DF2329BVF25V supports in-system programming without external high-voltage sources.
How many serial communication interfaces does the DF2329BVF25V support, and what protocols do they implement?
The DF2329BVF25V includes two independent Serial Communication Interface (SCI) modules, each supporting asynchronous full-duplex UART operation with programmable baud rates, parity, stop bits, and framing. They do not natively support synchronous protocols like SPI or I²C. Both SCIs are fully functional in all operating modes and can be used simultaneously-for example, one for host diagnostics and another for fieldbus communication. DF2329BVF25V's SCI modules comply with standard RS-232/RS-485 electrical interface requirements when paired with appropriate transceivers.
What analog peripherals are integrated into the DF2329BVF25V?
The DF2329BVF25V integrates a 10-bit successive-approximation A/D converter with 16 input channels and an 8-bit D/A converter with single output. The ADC supports software and timer-triggered conversions, selectable sample-and-hold time, and internal reference voltage. The DAC provides monotonic output with ±1 LSB integral nonlinearity. These analog resources are documented in Sections 17 and 18 of the H8S/2329 Group Hardware Manual. DF2329BVF25V uses these peripherals for sensor interfacing, closed-loop control feedback, and analog output generation without external converters.
Which package options are available for the DF2329BVF25V, and are they pin-compatible?
The DF2329BVF25V is offered in two package variants: FP-128B (128-ball fine-pitch BGA) and TFP-120 (120-pin thin fine-pitch QFP). While both share identical pin functions and signal assignments, they are not mechanically or solder-reflow compatible due to differing pin counts, pitch, and mounting methods. The FP-128B variant adds eight dedicated balls for power/ground distribution not present in the TFP-120. DF2329BVF25V's pinout diagrams are provided in Figures 1.7 and 1.8 of the Renesas Hardware Manual REJ09B0220-0600.
