For engineers reviewing the DF2329BVTE25WV datasheet, DF2329BVTE25WV pinout, DF2329BVTE25WV application, or DF2329BVTE25WV 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 management, and programmable logic subsystems.

Technical Context

The DF2329BVTE25WV implements the H8S/2000 32-bit internal architecture with 16-bit external data bus, supporting multiple operating modes (Mode 2–7) selected via MD0–MD2 pins. It integrates a 16-bit Timer Pulse Unit (TPU) with 8 channels, a 10-bit A/D converter with 16 inputs, and dual serial communication interfaces (SCI) supporting asynchronous and clock-synchronous protocols.

Flash memory is F-ZTAT™-type with guaranteed minimum 100 rewrite cycles, 10-year data retention, and programming time of 10–200 ms per 128-byte block. The device supports ROM-enabled and ROM-disabled expansion modes, with configurable chip select signals (CS0–CS7) controlled via DDR and CS167E/CS25E bits.

Key Specifications

Pinout & Package

DF2329BVTE25WV is housed in a 120-pin TFP (Thin Fine-Pitch) plastic QFP package (TFP-120), measuring 14 mm × 14 mm × 1.4 mm, with 0.4 mm lead pitch and exposed thermal pad. Pin functions are mode-dependent; key dedicated pins include RES (active-low reset), P20/PO0/TIOCA3 (I/O/timer output), and CS0–CS7 (chip select outputs).

FAQ

What is the maximum operating frequency of the DF2329BVTE25WV?

The DF2329BVTE25WV operates at a maximum clock frequency of 25 MHz, as specified in the H8S/2329 Group Hardware Manual Rev.6.00. This frequency determines instruction cycle timing, peripheral clock derivation, and real-time response limits. Operation above 25 MHz is not supported and may cause undefined behavior or failure to meet timing specifications for internal modules like the TPU or A/D converter. DF2329BVTE25WV must be used within this rated limit for guaranteed functionality.

Does the DF2329BVTE25WV include a D/A converter?

Yes, the DF2329BVTE25WV integrates a D/A converter as part of its on-chip peripheral set, confirmed in the Hardware Manual's overview (Page v) and peripheral function listing. This D/A converter supports analog output generation for applications such as actuator control or calibration signal injection. Its presence differentiates DF2329BVTE25WV from related variants like HD64F2328B, which omits the D/A block while retaining identical TPU, SCI, and A/D capabilities.

What package type is used for the DF2329BVTE25WV?

The DF2329BVTE25WV uses the TFP-120 (Thin Fine-Pitch) 120-pin QFP package, as documented in Figure 1.7 of the H8S/2329 Group Hardware Manual Rev.6.00. This package measures 14 mm × 14 mm × 1.4 mm with 0.4 mm lead pitch and includes an exposed thermal pad. Pin arrangement and mechanical dimensions are fully defined in Appendix F of the manual, confirming compatibility with standard 0.4 mm pitch reflow profiles and automated optical inspection.

How many rewrite cycles does the F-ZTAT™ flash memory in the DF2329BVTE25WV support?

The F-ZTAT™ flash memory in the DF2329BVTE25WV guarantees a minimum of 100 rewrite cycles, as stated in Section 19.4.1, 19.13.1, and 19.22.1 of the Hardware Manual, and confirmed in Table 22.22 (Flash Memory Characteristics). This specification applies across the full industrial temperature range and ensures reliable field firmware updates. The manual notes that 10,000 cycles is a reference value at 25°C but not guaranteed; design must rely on the 100-cycle minimum for lifetime validation.

Is the DF2329BVTE25WV pin-compatible with other H8S/2329 Group members?

No, the DF2329BVTE25WV is not universally pin-compatible across the H8S/2329 Group. While it shares the TFP-120 footprint with HD64F2329B (per Figure 1.7), variants like HD64F2329E use FP-128B (128-pin), and H8S/2324S uses TFP-100. Pin functions also vary by mode and variant - for example, WDTOVF is absent in F-ZTAT versions like DF2329BVTE25WV, whereas it appears on mask-ROM variants. Direct substitution requires verification of both package and pin function mapping per application.
