Renesas DF2117VT20HV

Overview

DF2117VT20HV 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 supports industrial temperature range (−40°C to +85°C). It is used in motor control and embedded automation systems requiring deterministic real-time response.

For engineers reviewing the DF2117VT20HV datasheet, DF2117VT20HV pinout, DF2117VT20HV application, or DF2117VT20HV equivalent, key selection criteria include its 100-pin LQFP package, 25 MHz max CPU clock, 128 KB flash with boot swap capability, dual PWM units supporting complementary outputs, and SCI with baud rate generator and framing error detection.

Technical Context

The DF2117VT20HV implements the H8S/2600 core architecture 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 synthesis and multiple clock sources including external crystal, ceramic resonator, or external clock input.

Peripheral subsystems include two independent TPU modules (TPU-A and TPU-B), each providing six 16-bit timer channels with capture/compare, PWM generation, and input edge detection. The SCI module supports asynchronous full-duplex communication with selectable baud rates, parity, and stop bits, and includes dedicated interrupt request lines per channel.

Key Specifications

Pinout & Package

DF2117VT20HV is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are multiplexed across 82 I/O lines, including dedicated TPU-A/B PWM outputs (e.g., PWMU0A–PWMU5A, PWMU0B–PWMU5B), SCI serial I/O (RxD/TxD/SCK), and external interrupt inputs (ExIRQ0–ExIRQ15).

FAQ

What is the maximum operating frequency of the DF2117VT20HV?

The DF2117VT20HV supports a maximum CPU clock frequency of 25 MHz. This is achieved using the on-chip PLL with external crystal input (e.g., 8 MHz XTAL × 3.125 = 25 MHz). The device maintains full functionality-including TPU timing accuracy and SCI baud rate stability-at this frequency across the full −40°C to +85°C temperature range. DF2117VT20HV datasheets specify timing margins for all internal paths at 25 MHz, confirming guaranteed operation without derating.

Does the DF2117VT20HV include an integrated ADC?

No, the DF2117VT20HV does not integrate an analog-to-digital converter. Its peripheral set includes TPU, SCI, WDT, and CPG-but no on-chip ADC. System designs requiring analog sensing must use external ADCs interfaced via SPI, I²C, or parallel GPIO, or select alternative Renesas parts such as the R5F21236TNNP (which includes 10-bit ADC). DF2117VT20HV's GPIO pins support analog input mode only as high-impedance inputs-not conversion capability.

What package type and pin count does the DF2117VT20HV use?

The DF2117VT20HV uses a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm lead pitch. This package includes 82 user-configurable I/O pins, 4 power/ground pairs, and dedicated clock/reset pins. The exposed thermal pad enhances thermal dissipation for sustained 25 MHz operation. DF2117VT20HV's pinout is documented in Section 8.2 of the H8S/2117 Hardware Manual (Rev. 3.00), confirming mechanical and soldering compatibility with JEDEC-standard LQFP-100 footprints.

Is the DF2117VT20HV qualified for automotive applications?

No, the DF2117VT20HV is rated for industrial temperature range (−40°C to +85°C) and classified as a "Standard" quality grade per Renesas documentation. It is not AEC-Q100 qualified and lacks automotive-specific features such as enhanced ESD protection, extended temperature screening, or fault injection test coverage. For automotive use, Renesas recommends the R5F21276TNNP (AEC-Q100 Grade 2) or RH850/F1L series. DF2117VT20HV is intended for industrial, commercial, and consumer equipment per Renesas' quality grade definitions.

How much on-chip flash memory does the DF2117VT20HV have?

The DF2117VT20HV contains 128 KB of on-chip flash memory organized in 1 KB sectors, supporting byte/word programming and block erase. It includes a dedicated 4 KB boot swap area for safe firmware updates-allowing background writes while executing from the active bank. DF2117VT20HV flash endurance is rated for 10,000 write/erase cycles with data retention of 20 years at 85°C, as specified in Renesas' H8S/2117 Group data sheets.
