Product details
Overview
DF2370VLP34V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2370 Group, featuring an H8S/2000 CPU core, 512 KB on-chip flash ROM, 32 KB RAM, and integrated peripherals including TPU, PPG, SCI, 10-bit A/D, 8-bit D/A, WDT, and DMAC. It operates at up to 25 MHz and supports multiple boot and memory expansion modes for embedded control applications.
For engineers reviewing the DF2370VLP34V datasheet, DF2370VLP34V pinout, DF2370VLP34V application, or DF2370VLP34V equivalent, key selection criteria include its 100-pin LQFP package, single-power flash (F-ZTAT™) reprogrammability, 3.3 V operation, and support for DRAM interfacing via high-functionality bus controller.
Technical Context
The DF2370VLP34V implements the H8S/2000 CPU with a 32-bit internal architecture, sixteen 16-bit general-purpose registers, and linear 16-Mbyte address space. It integrates dual DMA controllers (DMAC and EXDMAC) with external device handshaking (DACK/EDACK), enabling CPU-offload data transfers between external memory and peripherals.
Its peripheral set includes a 16-bit Timer Pulse Unit (TPU) with input capture/output compare, Programmable Pulse Generator (PPG), serial interfaces (SCI with IrDA support), and configurable I/O ports with address/data multiplexing capability in expanded modes - all operating under a single 3.3 V supply with industrial temperature range support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2370R | Renesas pin-compatible variant with identical core, memory, and peripheral set; differs only in mask ROM vs. flash (F-ZTAT™) configuration | Not field-upgradable - requires pre-programmed ROM image; suited for high-volume, fixed-function deployments | Select HD64F2370R only when firmware is finalized and no in-field updates are required. |
| R5F21276 | RL78/G13-series 16-bit MCU with 128 KB flash, lower power consumption, but reduced peripheral integration (no EXDMAC, no DRAM controller) | Better suited for battery-powered or ultra-low-power sensing nodes than high-throughput industrial control | Choose R5F21276 for energy-constrained designs where DRAM interfacing and high-speed DMA are unnecessary. |
Compared with DF2370VLP34V, HD64F2370R sacrifices field reprogrammability for cost-sensitive fixed-function use, while R5F21276 trades memory size, DRAM support, and EXDMAC capability for significantly lower active current - making each alternative optimal only within distinct design constraints.

FAQ
What is the maximum operating frequency of the DF2370VLP34V?
The DF2370VLP34V supports a maximum system clock frequency of 25 MHz. This rating is validated across the full industrial temperature range (−40°C to +85°C) and 3.3 V supply, enabling deterministic real-time performance for time-critical control tasks. The H8S/2000 CPU core delivers consistent instruction throughput at this frequency, with bus timing parameters specified in the hardware manual for external memory interface design.
Does the DF2370VLP34V support external DRAM interfacing?
Yes, the DF2370VLP34V includes a high-functionality bus controller that supports 64-Mbit synchronous DRAM (1 Mword × 16-bit × 4-bank) with automatic refresh and burst access. The controller provides dedicated RD/WR/AS/DS signals and CS0–CS3 chip selects, allowing direct connection without external glue logic - a capability confirmed in the H8S/2378 Group Hardware Manual Rev.7.00.
What type of flash memory does the DF2370VLP34V use?
The DF2370VLP34V uses Renesas' proprietary F-ZTAT™ flash technology - a single-power, 512 KB on-chip flash memory that supports in-system programming at standard 3.3 V supply. Unlike traditional flash requiring higher VPP voltages, F-ZTAT™ enables field firmware updates without hardware modification or special programmers, as documented in the H8S/2378 Group Hardware Manual.
How many analog-to-digital converter channels does the DF2370VLP34V have?
The DF2370VLP34V integrates a 10-bit successive-approximation A/D converter with 8 input channels. These channels are configurable for single-ended or differential input modes and support software or timer-triggered conversion - providing sufficient resolution and channel count for sensor monitoring in industrial control applications per the official hardware manual.
Is the DF2370VLP34V pin-compatible with other H8S/237x family members?
The DF2370VLP34V shares the same 100-pin LQFP package and core pinout with other H8S/237x Group MCUs (e.g., H8S/2378, H8S/2374), but functional pin assignments differ across variants due to varying peripheral sets and memory configurations. While mechanical compatibility exists, electrical and firmware compatibility require validation against the specific target part's hardware manual - especially for EXDMAC, TPU, and memory mapping features.
