Product details
Overview
DF2378BVLP35V from Renesas Electronics is a 16-bit single-chip microcontroller (MCU) based on the H8S/2000 CPU core, featuring 512 KB on-chip flash ROM, 32 KB RAM, and integrated peripherals including TPU, PPG, SCI/IrDA, 10-bit ADC, 8-bit DAC, DMAC/EXDMAC, DTC, WDT, and I²C interface. It operates at up to 33 MHz with 3.3 V supply and supports expanded memory addressing for industrial control and embedded instrumentation.
For engineers reviewing the DF2378BVLP35V datasheet, DF2378BVLP35V pinout, DF2378BVLP35V application, or DF2378BVLP35V equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative MCUs for system-level design continuity and BOM flexibility.
Technical Context
The DF2378BVLP35V implements the H8S/2000 32-bit internal architecture with sixteen 16-bit general-purpose registers and a 16-Mbyte linear address space. It supports multiple operating modes-including user boot mode (Mode 5), expanded mode with on-chip ROM enabled (Mode 4), and single-chip activation expanded mode (Mode 7)-to configure memory mapping and peripheral access dynamically.
Its EXDMA controller enables high-speed data transfer between external memory and external devices with DACK signaling, supporting fixed, incrementing, or decrementing source/destination address update modes. The TPU provides precise pulse-width modulation and input capture, while the DTC offloads CPU for efficient peripheral-triggered transfers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21278SNFP | Same H8S/2300 lineage but with 256 KB flash, 20 KB RAM, and no EXDMA; uses 100-pin QFP package. | Limited memory and no EXDMA reduce suitability for high-throughput data acquisition or large firmware images. | Select when cost-sensitive designs require basic H8S functionality without external memory expansion or burst DMA. |
| HD64F2378R | Pin-compatible variant with identical flash/RAM specs but enhanced ESD tolerance (±4 kV HBM) and extended temperature range (−40°C to +105°C). | Better suited for automotive under-hood or industrial environments where thermal stress and transient immunity are critical. | Choose HD64F2378R for harsh-environment deployments where DF2378BVLP35V's standard industrial grade (−20°C to +75°C) is insufficient. |
Compared with DF2378BVLP35V, R5F21278SNFP trades memory and DMA capability for lower cost and smaller footprint, while HD64F2378R retains full functional equivalence with improved ruggedness-making it a drop-in upgrade for reliability-critical deployments.

FAQ
What is the maximum operating frequency of the DF2378BVLP35V?
The DF2378BVLP35V operates at a maximum clock frequency of 33 MHz. This speed is achieved using an external crystal or oscillator connected to the main clock input, and it defines the upper limit for instruction execution, peripheral timing, and bus bandwidth. The DF2378BVLP35V maintains full functionality-including ADC conversion, TPU pulse generation, and SCI communication-at this rated frequency under specified 3.3 V supply and temperature conditions.
Does the DF2378BVLP35V include on-chip flash memory, and is it reprogrammable?
Yes, the DF2378BVLP35V integrates 512 KB of on-chip F-ZTAT™ flash memory. This flash is fully reprogrammable in-system (ISP) without requiring device removal or external programming hardware. Firmware updates can be performed via SCI or other supported interfaces, making the DF2378BVLP35V suitable for field-deployed equipment requiring post-production feature enhancements or bug fixes.
What peripheral modules are integrated into the DF2378BVLP35V?
The DF2378BVLP35V integrates a comprehensive set of peripherals: 16-bit Timer Pulse Unit (TPU), Programmable Pulse Generator (PPG), 8-bit Timer (TMR), Watchdog Timer (WDT), Serial Communication Interface (SCI) with IrDA support, 10-bit Analog-to-Digital Converter (ADC) with 8 channels, 8-bit Digital-to-Analog Converter (DAC) with 2 channels, Direct Memory Access Controller (DMAC), Extended DMA Controller (EXDMAC), Data Transfer Controller (DTC), and optional I²C interface (IIC2). These modules enable self-contained control, measurement, and communication capabilities.
Is the DF2378BVLP35V pin-compatible with other H8S/2300 series MCUs?
The DF2378BVLP35V shares the same 120-pin LQFP package and core pinout with the HD64F2378R variant, including identical address/data bus assignments, peripheral function mappings, and power/ground pin locations. However, it is not pin-compatible with lower-pin-count variants (e.g., 100-pin QFP H8S/2374 or 80-pin QFP H8S/2370) due to differing pin counts, signal multiplexing, and package dimensions.
What is the operating voltage range and temperature grade for the DF2378BVLP35V?
The DF2378BVLP35V operates from 3.3 V ±0.3 V (i.e., 3.0 V to 3.6 V) and is rated for the Standard quality grade per Renesas classification, supporting industrial applications within −20°C to +75°C ambient temperature. It is intended for use in computers, office equipment, communications gear, test instruments, audiovisual systems, home appliances, machine tools, and industrial robots-not for safety-critical, automotive, or life-support systems unless explicitly qualified.
