Product details
Overview
DF2328BVTE25V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2328 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, WDT, and DMAC. It operates at up to 25 MHz and targets embedded control systems requiring reprogrammable firmware and deterministic real-time response.
For engineers reviewing the DF2328BVTE25V datasheet, DF2328BVTE25V pinout, DF2328BVTE25V application, or DF2328BVTE25V equivalent, key selection criteria include its 256 KB flash endurance (≥100 rewrites), 10-year data retention, 25 MHz max clock frequency, and support for ROM-enabled expansion mode with configurable chip select outputs.
Technical Context
The DF2328BVTE25V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting multiple operating modes (Mode 2–Mode 7) selected via MD0–MD2 pins. Its flash memory uses F-ZTAT™ technology enabling in-system programming without UV erasure or external high-voltage supply.
Peripheral integration includes a 16-bit Timer Pulse Unit (TPU) with 8 channels, asynchronous serial interface (SCI) with programmable baud rates (e.g., 9600 bps @ 25 MHz with 0.47% error), 10-bit A/D converter (8-channel), and 8-bit D/A converter. The device supports power-down and bus-released states for low-power operation.

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 | Same H8S/2328 Group silicon; differs only in marking and packaging (HD64F2328B uses FP-128B package, while DF2328BVTE25V uses TFP-120). Identical electrical specs and pinout mapping. | FP-128B has 128 pins and 0.65 mm pitch; TFP-120 has 120 pins and 0.4 mm pitch - impacts PCB layout density and reflow profile. | Select HD64F2328B only if legacy FP-128B footprint compatibility is required; otherwise DF2328BVTE25V offers finer pitch and smaller footprint. |
| H8S/2329 Group (e.g., HD64F2329B) | Higher memory variant: 512 KB flash + 32 KB RAM; identical peripheral set and pin-compatible in TFP-120 package. No difference in clock speed or I/O structure. | Suitable for applications needing larger firmware images or extended data logging buffers - adds cost without benefit in memory-constrained designs. | Choose HD64F2329B only when firmware exceeds 256 KB or RAM usage exceeds 16 KB; DF2328BVTE25V remains optimal for cost-sensitive, fixed-function control. |
Compared with HD64F2328B, DF2328BVTE25V delivers identical functionality in a denser 0.4 mm pitch package, reducing PCB area by ~22%; versus HD64F2329B, it provides the same real-time peripheral performance at lower cost and power for applications not requiring >256 KB flash or >16 KB RAM.

FAQ
What is the maximum operating frequency of the DF2328BVTE25V?
The DF2328BVTE25V supports a maximum system clock frequency of 25 MHz, as confirmed in the H8S/2329 Group Hardware Manual Rev.6.00. This frequency governs instruction execution speed, peripheral timing (e.g., SCI baud rate generation), and A/D conversion sampling rate. Operation beyond 25 MHz is not characterized or guaranteed.
Does the DF2328BVTE25V include on-chip flash memory, and what are its endurance specifications?
Yes, the DF2328BVTE25V integrates 256 KB of F-ZTAT™ flash memory. Per Renesas documentation, it guarantees ≥100 rewrite cycles and 10-year data retention under specified operating conditions. Programming time is ≤200 ms per 128-byte block, and erase time is ≤1000 ms per block.
What package type is used for the DF2328BVTE25V, and how does it differ from other H8S/2328 variants?
The DF2328BVTE25V uses the TFP-120 package: a 120-pin thin fine-pitch QFP with 0.4 mm lead pitch. This differs from the FP-128B package (128 pins, 0.65 mm pitch) used in HD64F2328B. Pin functions and electrical characteristics are identical, but PCB layout and assembly requirements differ due to pitch and pin count.
Can the DF2328BVTE25V operate in low-power modes, and which modes are supported?
Yes, the DF2328BVTE25V supports Power-Down and Bus-Released states as defined in Section 2.8 of the Hardware Manual. In Power-Down mode, CPU and most peripherals halt while RAM contents are retained; wake-up occurs via interrupt or reset. Bus-Released mode disables the external bus interface to reduce system-level power consumption.
Is the DF2328BVTE25V pin-compatible with other devices in the H8S/2328 Group, such as HD64F2328B?
No - DF2328BVTE25V (TFP-120, 120-pin) and HD64F2328B (FP-128B, 128-pin) have different pin counts and pitches, making them physically incompatible. However, their pin *functions* and electrical behavior are identical where overlapping pins exist; redesign is required to migrate between packages.
