Product details
Overview
DF2166VT33WV from Renesas Electronics is a 16-bit single-chip microcontroller (MCU) based on the H8S/2166 Group, featuring an H8S/2000 CPU core, 256 KB on-chip ROM, 16 KB RAM, 16-bit FRT timer, dual PWM modules, SCI and I²C interfaces, and 8-channel 10-bit A/D converter - deployed in industrial control systems requiring deterministic real-time response.
For engineers reviewing the DF2166VT33WV datasheet, DF2166VT33WV pinout, DF2166VT33WV application, or DF2166VT33WV equivalent, key selection considerations include its 3.3 V operation, 48 MHz max CPU clock, 100-pin LQFP package, flash-based program memory with on-chip emulation support, and integrated peripheral set for embedded motion control and sensor interface applications.
Technical Context
The DF2166VT33WV implements the H8S/2000 CPU architecture with sixteen 16-bit general-purpose registers, 16-Mbyte linear address space, and object-level upward compatibility with H8/300 and H8/300H instruction sets. It supports two operating modes - single-chip and external bus - with boot programming, on-chip emulation, and boundary scan capabilities.
Peripheral integration includes a data transfer controller (DTC) acting as bus master, dual PWM timers (PWM and PWMX), watchdog timer (WDT), LPC interface, D/A converter, and I/O ports with programmable pull-up resistors. All peripherals are synchronized to the same internal clock domain and share register-mapped access via the AMBA-like bus structure.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21266SDFP | Same H8S/2166 core, identical pinout and peripheral set, but 3.3 V-only operation and no 5 V-tolerant I/O | Requires strict 3.3 V system design; lacks legacy 5 V interface capability of DF2166VT33WV | Select when migrating to newer Renesas packaging and simplified power rail architecture |
| HD64F2166FV | Same silicon die, but OTP ROM instead of flash; no in-field reprogramming capability | Suitable only for fixed-function, high-volume production where firmware never changes | Choose for cost-sensitive applications with immutable code and no need for field updates |
Compared with DF2166VT33WV, R5F21266SDFP offers identical functionality in a newer package with tighter thermal specs, while HD64F2166FV trades flash flexibility for lower unit cost and guaranteed code immutability - making DF2166VT33WV optimal for prototyping and firmware-upgradable industrial devices.

FAQ
What is the maximum operating frequency of the DF2166VT33WV?
The DF2166VT33WV supports a maximum CPU clock frequency of 48 MHz, achieved via internal PLL multiplication of an external 1–20 MHz clock source applied to the CLKIN pin. This frequency is guaranteed under 3.3 V ±0.3 V supply and within the –40°C to +85°C industrial temperature range specified for the DF2166VT33WV.
Does the DF2166VT33WV include on-chip debug capability?
Yes, the DF2166VT33WV integrates on-chip emulation support compliant with the H-UDI standard, enabling real-time debugging, breakpoint setting, register inspection, and trace without external in-circuit emulators. This capability is active in both single-chip and external bus modes and is fully supported by Renesas' High-performance Embedded Workshop IDE for the DF2166VT33WV.
Is the DF2166VT33WV pin-compatible with other H8S/2166 family members?
Yes, the DF2166VT33WV shares identical 100-pin LQFP pinout and signal mapping with HD64F2166FV and R5F21266SDFP variants. All three parts maintain consistent power, reset, clock, and peripheral pin assignments - allowing direct PCB reuse when migrating between flash, OTP, and newer-package versions of the same H8S/2166 silicon.
What type of memory technology is used for program storage in the DF2166VT33WV?
The DF2166VT33WV uses F-ZTAT™ flash memory for its 256 KB on-chip program storage. This Renesas proprietary flash technology supports block erase, byte programming, and in-system reprogramming via the on-chip bootloader - enabling firmware updates in the field without removing the DF2166VT33WV from the target system.
Can the DF2166VT33WV operate with a 5 V supply?
No, the DF2166VT33WV is strictly a 3.3 V device: it requires VCC = 3.3 V ±0.3 V and is not 5 V tolerant on any I/O pin. Applying 5 V to inputs or supply pins risks permanent damage. For mixed-voltage systems, level-shifting circuitry must be used between the DF2166VT33WV and any 5 V peripherals or buses.
