Overview

DF2329BVTE25V 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 DF2329BVTE25V datasheet, DF2329BVTE25V pinout, DF2329BVTE25V application, or DF2329BVTE25V equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options for industrial control, motor drive, and instrumentation designs.

Technical Context

The DF2329BVTE25V 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 successive-approximation A/D converter with 16 inputs, and a 8-bit D/A converter.

It features dual serial interfaces (SCI) supporting asynchronous communication, a watchdog timer with independent clock source, and a data transfer controller (DTC) that offloads CPU during memory-to-peripheral transfers. Flash memory supports ≥100 rewrite cycles with 10-year data retention and block erase times of 50–1000 ms.

FAQ

What is the maximum operating frequency of the DF2329BVTE25V?

The DF2329BVTE25V supports a maximum operating frequency of 25 MHz, achieved with an external crystal or clock source connected to the CLK pin. This frequency determines instruction execution speed (up to 25 MIPS), peripheral timing budgets, and maximum baud rates for SCI communication. Operation above 25 MHz is not supported and may cause undefined behavior or timing violations in on-chip modules such as the A/D converter or TPU.

Does the DF2329BVTE25V include on-chip flash memory, and what are its endurance specifications?

Yes, the DF2329BVTE25V integrates 256 KB of F-ZTAT™ flash memory. Its endurance is specified at a minimum of 100 write/erase cycles, with typical performance exceeding 10,000 cycles under standard conditions (25°C). Data retention is guaranteed for 10 years after the final programming cycle, and block erase time ranges from 50 ms (typical) to 1000 ms (maximum) per 1 KB block.

How many analog-to-digital and digital-to-analog channels does the DF2329BVTE25V support?

The DF2329BVTE25V includes a 10-bit successive-approximation A/D converter with 16 input channels and two independent 8-bit D/A converters. The A/D converter supports programmable sample-and-hold timing and scan mode for sequential channel acquisition, while the D/A outputs provide voltage references or analog setpoints without external DAC components - critical for closed-loop control in DF2329BVTE25V-based systems.

What package type is used for the DF2329BVTE25V, and what are its key mechanical features?

The DF2329BVTE25V is packaged in a 120-pin Thin Fine-Pitch QFP (TFP-120) with 0.4 mm lead pitch and dimensions of 14 mm × 14 mm × 1.4 mm. It features an exposed thermal pad on the underside for improved heat dissipation, making it suitable for industrial environments where ambient temperatures exceed 70°C. This package is distinct from the FP-128B variant used by HD64F2329E.

Can the DF2329BVTE25V operate in low-power modes, and which peripherals remain active during sleep?

Yes, the DF2329BVTE25V supports multiple low-power modes including Stop and Sleep. In Stop mode, the CPU and most peripherals halt while the watchdog timer and real-time clock (if enabled via external oscillator) continue running. In Sleep mode, the CPU stops but peripheral clocks remain active, allowing SCI, TPU, and A/D to trigger wake-up interrupts - enabling responsive, energy-efficient operation in battery-powered DF2329BVTE25V applications.
