Renesas DF2117VBG20V

Overview

DF2117VBG20V 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 capability. It operates at up to 25 MHz with 3.3 V supply and targets embedded control applications requiring deterministic real-time response.

For engineers reviewing the DF2117VBG20V datasheet, DF2117VBG20V pinout, DF2117VBG20V application, or DF2117VBG20V equivalent, key selection criteria include its 100-pin LQFP package, 16-channel PWM support via two independent PWM units (PWMU_A/PWMU_B), dual SCI channels for asynchronous serial communication, and built-in clock pulse generator (CPG) with PLL for flexible system clock synthesis.

Technical Context

The DF2117VBG20V implements the H8S CPU core with 16-bit data bus and 24-bit address space, supporting both big-endian and little-endian operation modes via software configuration. Its peripheral set includes two 16-bit TPU modules (TPU0/TPU1), each with six independent timer channels supporting input capture, output compare, and PWM generation with dead-time insertion capability.

System-level timing is managed by the CPG, which accepts external crystal (1–20 MHz) or ceramic resonator inputs and generates internal clocks including φ (main), φ/2, φ/4, and φ/8 via programmable dividers and a PLL multiplier (×1 to ×4). The interrupt controller supports 128 vectors with priority encoding and nested interrupt handling.

FAQ

What is the maximum operating frequency of the DF2117VBG20V and what supply voltage does it require?

The DF2117VBG20V operates at a maximum frequency of 25 MHz and requires a supply voltage range of 3.0 V to 3.6 V. This 3.3 V nominal operation aligns with standard industrial logic levels and ensures compatibility with common level-shifting and interface components. The DF2117VBG20V achieves this speed using an on-chip PLL with programmable multiplication and division ratios, allowing stable high-frequency operation even with low-cost external crystals.

Does the DF2117VBG20V support in-system programming (ISP) of its on-chip Flash memory?

Yes, the DF2117VBG20V supports in-application programming (IAP) of its 128 KB Flash memory through the on-chip bootloader and dedicated Flash control registers. This capability allows firmware updates in the field without requiring external programming hardware. The DF2117VBG20V implements block-wise erase (1 KB sectors) and byte/word programming with built-in erase/write verification, enabling robust over-the-air (OTA) update mechanisms in deployed systems.

How many independent PWM output channels does the DF2117VBG20V provide, and what resolution do they offer?

The DF2117VBG20V provides 16 independent PWM output channels - 8 from PWMU_A and 8 from PWMU_B - each with 8-bit resolution (256 steps). These channels support synchronized update, programmable dead-time insertion, and fault input monitoring. The DF2117VBG20V uses its TPU timer resources to generate precise PWM waveforms, making it suitable for three-phase motor control and digital power supply regulation where timing coherence across multiple outputs is essential.

What serial communication interfaces are integrated into the DF2117VBG20V?

The DF2117VBG20V integrates two full-duplex Serial Communication Interface (SCI) channels, each with independent baud rate generators, 8-byte transmit/receive FIFO buffers, parity checking, and framing error detection. One SCI channel supports low-speed operation (LSCI) for direct connection to LCD modules, while both channels implement LIN-compliant break detection. The DF2117VBG20V uses these interfaces for reliable host-to-peripheral communication in industrial and automotive subsystems.

Is the DF2117VBG20V qualified for automotive applications?

No, the DF2117VBG20V is classified as a Standard quality grade device per Renesas documentation and is intended for applications such as industrial equipment, office automation, and consumer electronics - not automotive or safety-critical systems. It is not AEC-Q100 qualified, lacks automotive-grade temperature range (-40°C to +125°C), and does not include features like ISO 26262-ready lockstep cores. For automotive use, Renesas recommends the RH850 or RL78/F1x families instead of the DF2117VBG20V.
