Overview
DF2367VF33V from Renesas Electronics is a 16-bit single-chip microcontroller (MCU) in the H8S/2367F group, featuring an H8S/2600 CPU core, 384 KB on-chip ROM, 32 KB RAM, and integrated peripherals including a 10-bit A/D converter, 8-bit D/A converter, TPU, PPG, SCI/IrDA, I²C, and DMAC/DTC. It operates at 33 MHz with 3.3 V supply and targets industrial control and embedded instrumentation.
For engineers reviewing the DF2367VF33V datasheet, DF2367VF33V pinout, DF2367VF33V application, or DF2367VF33V equivalent, key selection criteria include its 128-pin QFP package, 33 MHz max clock, 3.3 V operation, flash memory programmability, and peripheral integration for real-time control systems requiring deterministic timing and mixed-signal interfacing.
Technical Context
The DF2367VF33V implements the H8S/2600 CPU with a 32-bit internal architecture, sixteen 16-bit general-purpose registers, and a 16-Mbyte linear address space. It supports multiple operating modes-including boot, expanded, and user boot-enabling flexible memory mapping between on-chip ROM (384 KB), on-chip RAM (32 KB), and external address space.
Its peripheral set includes dual serial interfaces (SCI with IrDA support and optional I²C bus interface 2), a 16-bit timer pulse unit (TPU) with PWM and input capture, a programmable pulse generator (PPG), watchdog timer (WDT), and direct memory access controller (DMAC) with data transfer controller (DTC) co-processor for efficient peripheral-to-memory transfers without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2367FV | Same silicon die and pinout; differs only in marking and packaging - HD64F2367FV is the legacy NEC part number for identical functionality | No functional difference; used interchangeably in legacy designs where original part number sourcing is required | Select HD64F2367FV only when documentation or procurement mandates legacy nomenclature compliance |
| R5F2367CDFP | Successor in Renesas RL78/G14 family: 16-bit core, 128 KB flash, 12 KB RAM, 32 MHz, but different instruction set and peripheral register map | Requires full firmware porting; lacks TPU and PPG, but adds low-power modes and enhanced SCI with LIN support | Choose R5F2367CDFP for new designs prioritizing ultra-low power, longer battery life, or LIN bus integration over legacy code reuse |
Compared with HD64F2367FV, DF2367VF33V offers identical electrical and functional behavior under Renesas branding; versus R5F2367CDFP, it trades modern power efficiency and LIN capability for proven real-time determinism, mature toolchain support, and direct compatibility with existing H8S-based firmware and hardware.

FAQ
What is the maximum operating frequency of the DF2367VF33V?
The DF2367VF33V operates at a maximum system clock frequency of 33 MHz. This rating is guaranteed across the full industrial temperature range (−40°C to +85°C) and 3.3 V ±0.3 V supply voltage. The clock is derived from an external crystal (1–20 MHz) multiplied by the on-chip PLL, and timing-critical peripherals like the TPU and A/D converter are synchronized to this master clock. DF2367VF33V maintains instruction execution throughput and interrupt latency specifications only when operated within this validated frequency envelope.
Does the DF2367VF33V include on-chip flash memory, and is it reprogrammable?
Yes, the DF2367VF33V integrates 384 KB of on-chip F-ZTAT™ flash memory, which supports in-system programming (ISP) using standard 3.3 V supply-no external high-voltage programmer is required. Firmware updates, calibration data writes, and field patches can be performed via SCI or internal bootloader routines. DF2367VF33V flash endurance is rated for 10,000 write/erase cycles with data retention exceeding 20 years at 85°C, making it suitable for applications requiring infrequent but reliable field updates.
What analog peripherals are integrated into the DF2367VF33V?
The DF2367VF33V integrates a 10-bit successive approximation register (SAR) analog-to-digital converter with 8 input channels and sample-and-hold, plus an 8-bit voltage-output digital-to-analog converter. These peripherals share dedicated analog power (AVCC/AVSS) and reference pins (VREFH/VREFL), supporting ratiometric measurements and precision actuator control. DF2367VF33V's A/D converter achieves ±1 LSB integral nonlinearity and 70 dB SNR at 100 kSPS, while the D/A provides monotonic output with ±1 LSB accuracy across its full scale.
Is the DF2367VF33V pin-compatible with other members of the H8S/236x family?
The DF2367VF33V shares the same 128-pin QFP package and core pinout with the H8S/2368F and H8S/2364F, but differences exist in on-chip memory size, peripheral enablement, and certain pin functions (e.g., I²C2 availability). While PCB layout may be reused across these variants, firmware and power sequencing must be verified per device-specific datasheet. DF2367VF33V is not pin-compatible with the smaller-pin-count H8S/2360F or H8S/2361F derivatives due to differing address/data bus widths and I/O allocations.
What development tools are supported for the DF2367VF33V?
Renesas provides full toolchain support for the DF2367VF33V, including the High-performance Embedded Workshop IDE (v4.04), H8S C/C++ Compiler v6.01, and H8S Simulator/Debugger. Third-party tools such as IAR Embedded Workbench for H8S also offer certified support. DF2367VF33V evaluation is enabled via the Renesas E8 emulator and compatible target boards with JTAG debugging interface. All tools target the H8S/2600 instruction set and register model defined in the H8S/2600 Series Software Manual (REJ09B0139).
