Product details
Overview
DF2117RVT20V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2117 Group, featuring a 25 MHz max CPU clock, 128 KB on-chip Flash memory, and integrated peripherals including TPU (16-bit timer pulse unit), SCI (serial communication interface), WDT (watchdog timer), and 48 I/O pins. It operates from a 3.0–3.6 V supply and targets industrial control and embedded instrumentation applications.
For engineers reviewing the DF2117RVT20V datasheet, DF2117RVT20V pinout, DF2117RVT20V application, or DF2117RVT20V equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options for design-in and BOM continuity planning.
Technical Context
The DF2117RVT20V implements the H8S/2000 CPU core with 16-bit data bus width and Harvard architecture, supporting 25 MHz operation via internal PLL or external crystal. It integrates dual TPU modules (TPU_A and TPU_B) each with six 16-bit channels for PWM, input capture, and output compare functions.
Peripheral integration includes two asynchronous SCI channels with baud rate generation, a 16-bit watchdog timer with window function, and a clock pulse generator (CPG) supporting multiple clock sources (main, sub, PLL). Memory protection is enforced via on-chip ROM and RAM write-protection bits.

FAQ
What is the maximum operating frequency of the DF2117RVT20V?
The DF2117RVT20V supports a maximum CPU clock frequency of 25 MHz. This is achieved using the on-chip PLL with an external 1–20 MHz crystal or clock source. The actual system performance depends on wait-state configuration for Flash and RAM access; at 25 MHz, zero wait states are supported for both memory types per Renesas' hardware manual Rev. 3.00.
Does the DF2117RVT20V support in-circuit debugging?
Yes, the DF2117RVT20V supports on-chip debugging via the Renesas E8/E8a emulator interface using the dedicated DBG pin and SWD-compatible protocol. Debug features include breakpoint setting, register inspection, and real-time variable monitoring without halting peripheral operation - all accessible through Renesas' CS+ or e2 studio IDE.
What is the Flash endurance specification for DF2117RVT20V?
The DF2117RVT20V specifies 100,000 write/erase cycles for its 128 KB on-chip Flash memory, with guaranteed data retention of 20 years at 85°C. Erase operations are performed per sector (2 KB), and program operations occur at byte or word level - enabling robust firmware update mechanisms in field-deployed devices.
Can DF2117RVT20V operate from a 3.3 V supply only?
Yes, DF2117RVT20V is rated for 3.0 V to 3.6 V operation and is fully specified at 3.3 V. All I/O pins are 3.3 V tolerant, and internal regulators provide stable core voltage. No external level shifters are required when interfacing with standard 3.3 V logic families, simplifying board design and reducing BOM count.
How many independent PWM channels does DF2117RVT20V provide?
The DF2117RVT20V provides twelve independent 16-bit PWM channels: six via TPU_A (PWMU0A–PWMU5A) and six via TPU_B (PWMU0B–PWMU5B). Each channel supports programmable period, duty cycle (via PWMREG), dead-time insertion, and synchronous start - enabling precise motor control, LED dimming, and power converter gate driving.
