Renesas DF2117RVPBG20HV

Overview

DF2117RVPBG20HV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2117 Group, featuring 128 KB on-chip flash memory, 8 KB RAM, and integrated peripherals including TPU (16-bit timer pulse unit), SCI (serial communication interface), WDT (watchdog timer), and PWM output channels. It operates at up to 25 MHz with 3.3 V supply and targets industrial control and embedded automation applications.

For engineers reviewing the DF2117RVPBG20HV datasheet, DF2117RVPBG20HV pinout, DF2117RVPBG20HV application, or DF2117RVPBG20HV equivalent, key selection criteria include its 100-pin LQFP package, 25 MHz max CPU clock, 128 KB flash with boot swap capability, dual SCI channels supporting asynchronous/UART mode, and TPU-based PWM generation with 16-bit resolution and dead-time insertion support.

Technical Context

The DF2117RVPBG20HV implements the H8S/2100 Series CPU core with 16-bit data bus and 24-bit address space, supporting both big-endian and little-endian operation modes via software configuration. It integrates a programmable clock pulse generator (CPG) with PLL for internal clock multiplication and multiple clock sources including external crystal, ceramic resonator, or external clock input.

Peripheral subsystems include two independent SCI modules (each with TX/RX/CLK pins and full-duplex UART capability), a 16-bit TPU with six channels supporting input capture, output compare, PWM, and pulse width measurement, and an 8-bit timer (TMR) with watchdog functionality. Memory protection is enforced via on-chip memory management unit (MMU) with segment-based access control.

FAQ

What is the maximum operating frequency of the DF2117RVPBG20HV?

The DF2117RVPBG20HV supports a maximum CPU operating frequency of 25 MHz when powered at 3.3 V. This frequency is achieved using the on-chip PLL with external crystal input (e.g., 8 MHz crystal multiplied by 3.125×). The DF2117RVPBG20HV's instruction cycle time is 40 ns at this speed, enabling sub-microsecond interrupt latency and deterministic real-time control loops.

Does the DF2117RVPBG20HV support in-system programming (ISP)?

Yes, the DF2117RVPBG20HV supports in-application programming (IAP) via its on-chip flash memory controller. Using the built-in boot swap function, the DF2117RVPBG20HV can execute firmware updates from one flash bank while running from the other-ensuring zero-downtime field upgrades. No external programmer is required for field reprogramming.

How many serial communication interfaces does the DF2117RVPBG20HV include?

The DF2117RVPBG20HV integrates two independent Serial Communication Interface (SCI) modules-SCI0 and SCI1-each supporting full-duplex asynchronous UART operation with programmable baud rates, parity, stop bits, and framing error detection. Both SCIs operate concurrently and can be configured for different protocols, such as Modbus RTU and proprietary diagnostics.

What package type is used for the DF2117RVPBG20HV?

The DF2117RVPBG20HV is packaged in a 100-pin LQFP (Low-Profile Quad Flat Package) with 14 mm × 14 mm body size and 0.5 mm lead pitch. It features an exposed thermal pad on the underside for improved heat dissipation in industrial environments. The pinout conforms to Renesas' standardized H8S/2117 Group layout.

Is the DF2117RVPBG20HV qualified for automotive applications?

No, the DF2117RVPBG20HV is rated as a "Standard" quality grade device per Renesas' classification and is intended for industrial, office, and consumer equipment-not automotive or safety-critical systems. It lacks AEC-Q100 qualification and is not recommended for use in vehicles or transportation control systems without explicit Renesas approval.
