Product details
Overview
DF2168VT33V from Renesas Electronics is a 16-bit single-chip microcontroller (MCU) based on the H8S/2168 Group, featuring an H8S/2000 CPU core, 512 KB on-chip flash memory, 32 KB RAM, and integrated peripherals including SCI, I²C, PWM timers, A/D and D/A converters, and a data transfer controller (DTC). It operates at up to 25 MHz with 3.3 V supply and targets embedded control in industrial and office equipment.
For engineers reviewing the DF2168VT33V datasheet, DF2168VT33V pinout, DF2168VT33V application, or DF2168VT33V equivalent, key selection criteria include its 16-bit H8S/2000 architecture, 512 KB flash with F-ZTAT™ technology, 3.3 V operation, 100-pin LQFP package, and support for single-chip and external bus modes - critical for legacy-compatible industrial control upgrades.
Technical Context
The DF2168VT33V implements the H8S/2000 CPU with a 32-bit internal data path, sixteen 16-bit general-purpose registers, and object-level upward compatibility with H8/300 and H8/300H instruction sets. Its memory subsystem includes 512 KB on-chip flash (F-ZTAT™), 32 KB RAM, and supports both linear 16-Mbyte addressing and dual operating modes (Normal/Advanced).
On-chip peripherals include two PWM timer modules (PWM and PWMX), a 16-bit free-running timer (FRT), 8-bit timer (TMR), watchdog timer (WDT), serial communication interface (SCI), I²C bus interface (IIC), LPC interface, 10-bit A/D converter (8 channels), 8-bit D/A converter (2 channels), and a bus-master DTC for efficient data movement - all accessible via a 16-bit internal bus enabling byte- and word-access in a single cycle.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21268SNFP | Same H8S/2168 family, identical pinout and peripheral set, but 3.3 V-only operation and updated Renesas part numbering | No functional deviation; direct migration path for new designs requiring current production support | Select R5F21268SNFP for new designs needing active manufacturing and long-term availability |
| HD64F2168F25 | Legacy NEC part number for same silicon; identical electrical specs and package, but obsolete status and limited distribution | Only suitable for legacy repair or continuity builds where original BOM must be preserved | Choose HD64F2168F25 only for exact form-fit-function replacement in end-of-life systems |
Compared with DF2168VT33V, R5F21268SNFP offers guaranteed supply and updated documentation, while HD64F2168F25 matches legacy sourcing needs but lacks future availability - making DF2168VT33V the optimal bridge for transitioning from obsolete to supported H8S/2168 variants.

FAQ
What is the maximum operating frequency of the DF2168VT33V?
The DF2168VT33V operates at a maximum clock frequency of 25 MHz. This rating is specified under 3.3 V supply and ambient temperatures from –20°C to +75°C. The H8S/2000 CPU core achieves single-cycle instruction execution at this speed due to its optimized 16-bit architecture and 16-bit internal bus, enabling deterministic real-time response in control applications. DF2168VT33V performance remains stable across its qualified temperature range when used with appropriate decoupling and clock source stability.
Does the DF2168VT33V support in-system programming of its flash memory?
Yes, the DF2168VT33V supports in-system programming (ISP) of its 512 KB on-chip flash memory via its built-in SCI interface or on-chip emulation circuitry. This capability eliminates the need for external programmers and allows field firmware updates without removing the DF2168VT33V from the target board. Programming is performed using Renesas' standard flash programming algorithms and is fully supported by the HEW (High-performance Embedded Workshop) development environment. DF2168VT33V flash endurance is rated for 10,000 write/erase cycles.
What analog peripherals are integrated into the DF2168VT33V?
The DF2168VT33V integrates a 10-bit successive-approximation register (SAR) analog-to-digital converter with 8 input channels and a conversion time of 1.2 µs per channel, plus two 8-bit voltage-output digital-to-analog converters. These analog blocks share common reference pins (AVCC/AVSS) and are synchronized with the system clock. The ADC supports software, timer, and external trigger sources, while the DACs provide rail-to-rail output swing. All analog functionality is fully specified in the DF2168VT33V hardware manual and validated across its operating voltage and temperature range.
Is the DF2168VT33V pin-compatible with other members of the H8S/2168 Group?
Yes, the DF2168VT33V is pin-compatible with other 100-pin LQFP variants in the H8S/2168 Group, including the R5F21268SNFP and HD64F2168F25. All share identical pin assignments, electrical characteristics, and package dimensions (14 mm × 14 mm, 0.5 mm pitch). Differences between these parts are limited to marking, packaging date codes, and production status - not pin function or timing. This allows drop-in replacement in existing PCB layouts when migrating from legacy to current Renesas part numbers, provided firmware accounts for any minor errata revisions.
What development tools are officially supported for the DF2168VT33V?
Renesas officially supports the High-performance Embedded Workshop (HEW) IDE with the H8S C/C++ compiler (ADE-702-247), H8S simulator/debugger (ADE-702-282), and the E8/E8a in-circuit emulators for DF2168VT33V development. These tools provide full register-aware debugging, flash programming, real-time trace, and peripheral simulation. The DF2168VT33V hardware manual (Rev. 3.00) and H8S/2000 programming manual (ADE-602-083) are required companion documents. No third-party toolchain has official Renesas certification for DF2168VT33V.
