Product details
Overview
DF2166VT33V from Renesas Electronics is a 16-bit single-chip microcontroller (MCU) in the H8S/2166 group, featuring an H8S/2000 CPU core, 256 KB on-chip flash memory, 16 KB RAM, and integrated peripherals including SCI, I²C, PWM timers, A/D converter, and 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 DF2166VT33V datasheet, DF2166VT33V pinout, DF2166VT33V application, or DF2166VT33V equivalent, key selection considerations include its 100-pin LQFP package, 3.3 V operation, flash-based programmability, and peripheral set optimized for real-time motor control, power management, and system monitoring applications.
Technical Context
The DF2166VT33V implements the H8S/2000 CPU architecture with sixteen 16-bit general-purpose registers, 16-Mbyte linear address space, and object-level instruction compatibility with H8/300H. It supports two operating modes-Normal and Advanced-with configurable address mapping and boot options.
On-chip peripherals include a 16-bit free-running timer (FRT), dual PWM timer modules (PWM and PWMX), 8-channel 10-bit A/D converter, 2-channel D/A converter, watchdog timer (WDT), and data transfer controller (DTC) acting as bus master for autonomous memory-to-peripheral transfers without CPU intervention.

FAQ
What is the maximum operating frequency of the DF2166VT33V?
The DF2166VT33V supports a maximum system clock frequency of 25 MHz. This is achieved using an external crystal or clock source applied to the CLKIN pin, optionally multiplied by the on-chip PLL. At this speed, the H8S/2000 CPU executes instructions with a 40 ns cycle time, enabling deterministic real-time control in applications such as motor drive and power regulation. The DF2166VT33V maintains full functionality and timing compliance across its specified −40°C to +85°C industrial temperature range at this frequency.
Does the DF2166VT33V include on-chip flash memory, and can it be reprogrammed in-system?
Yes, the DF2166VT33V integrates 256 KB of on-chip flash memory using Renesas' F-ZTAT™ technology. This flash supports in-system programming (ISP) via the on-chip bootloader, allowing firmware updates without removing the device from the target board. Programming is performed through the SCI interface or dedicated programming pins, and the DF2166VT33V supports sector erase, byte/word write, and read-while-write capability - essential for field-upgradable embedded systems.
What peripheral interfaces are available on the DF2166VT33V for communication with external devices?
The DF2166VT33V provides multiple standard communication interfaces: two independent Serial Communication Interfaces (SCI) supporting asynchronous UART operation, one I²C bus interface for multi-master sensor and EEPROM connectivity, and an LPC (Low Pin Count) interface for legacy peripheral bridging. All interfaces are implemented in hardware with dedicated registers and interrupt support, enabling concurrent operation without CPU polling. These peripherals are accessible via multiplexed pins on Port A and Port C, and their configuration is controlled through dedicated module registers in the DF2166VT33V memory map.
Is the DF2166VT33V pin-compatible with other members of the H8S/216x family?
Yes, the DF2166VT33V is pin-compatible with the HD64F2167 and HD64F2168 in the same 100-pin LQFP package. This allows direct hardware substitution within the same footprint when upgrading memory size (e.g., from 256 KB to 512 KB flash in the DF2166VT33V → HD64F2168 migration) or adding features like enhanced PWMX functionality. Pin assignments for power, reset, clock, and primary I/O remain identical across these variants, ensuring PCB reuse and minimizing redesign effort for DF2166VT33V-based systems.
What development tools are officially supported for the DF2166VT33V?
Renesas provides full toolchain support for the DF2166VT33V, including the High-performance Embedded Workshop IDE, H8S C/C++ Compiler (ADE-702-247), and H8S Simulator/Debugger (ADE-702-282). Hardware debug is enabled via the on-chip emulation interface compliant with IEEE 1149.1, supporting real-time trace, breakpoint, and register inspection. Renesas also publishes the H8S/2168 Group Hardware Manual (Rev. 3.00) and H8S/2000 Series Programming Manual (ADE-602-083) - both explicitly cover DF2166VT33V register definitions, timing diagrams, and peripheral usage examples.
