Renesas DF2280F20BJV

Overview

DF2280F20BJV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2280 Group, featuring an H8S/2000 CPU core, 256 KB flash memory (F-ZTAT™), 16 KB RAM, 16-bit timer pulse unit, and integrated A/D converter. It operates at up to 20 MHz, supports 3.3 V or 5 V supply, and targets embedded control systems requiring field-upgradable firmware and mixed-signal integration.

For engineers reviewing the DF2280F20BJV datasheet, DF2280F20BJV pinout, DF2280F20BJV application, or DF2280F20BJV equivalent, key selection criteria include its flash reprogrammability, on-chip motor control PWM timer, LCD controller/driver capability, and absence of CAN interface - distinguishing it from the H8S/2282 Group.

Technical Context

The DF2280F20BJV implements the H8S/2000 CPU architecture with advanced mode support, 24-bit address space, and register-based interrupt handling. It integrates a clock pulse generator with PLL for internal clock synthesis and supports multiple low-power wait modes via the system control register (SYSCR) and mode control register (MDCR).

Peripheral integration includes a 10-channel 10-bit A/D converter with sample-and-hold, serial communication interfaces (SCI ×2), watchdog timer, and motor control PWM timer with complementary output and dead-time insertion - all mapped to dedicated I/O ports with configurable pull-up resistors and CMOS/TTL-compatible levels.

Key Specifications

Pinout & Package

DF2280F20BJV is housed in a 128-pin LQFP (14 mm × 14 mm, 0.4 mm pitch) package with exposed thermal pad. Pin functions are defined per operating mode (normal/advanced) and include multiplexed I/O, dedicated reset, clock inputs (XIN/XOUT), and power/ground distribution optimized for noise immunity in motor control environments.

FAQ

What is the maximum operating frequency of the DF2280F20BJV?

The DF2280F20BJV operates at a maximum CPU clock frequency of 20 MHz. This frequency is achieved using the on-chip PLL clock pulse generator with an external crystal (1–20 MHz) or clock source. The 20 MHz limit defines instruction execution speed, peripheral timing resolution, and real-time responsiveness in control loops implemented on the DF2280F20BJV.

Does the DF2280F20BJV include a CAN interface?

No, the DF2280F20BJV does not include a controller area network (CAN) interface. Unlike the H8S/2282 Group, the H8S/2280 Group - which includes the DF2280F20BJV - explicitly omits the CAN module. System designs requiring CAN communication must implement external transceivers with software-managed protocols or select alternative MCUs such as the H8S/2282F series.

What type of flash memory is used in the DF2280F20BJV?

The DF2280F20BJV uses F-ZTAT™ flash memory - a Renesas proprietary fast-zero-time-access technology. This 256 KB on-chip flash supports in-system programming (ISP) without high-voltage programming, enabling field firmware updates and rapid prototyping. Its endurance and data retention meet industrial requirements, making it suitable for long-lifecycle embedded products using the DF2280F20BJV.

Is the DF2280F20BJV pin-compatible with other H8S/2280 variants?

Yes, the DF2280F20BJV shares the same 128-pin LQFP package and pinout with other members of the H8S/2280 Group, including HD64F2280B and HD64F2280RB. However, functional differences exist - notably, DF2280F20BJV includes the LCD controller/driver while HD64F2280RB does not. Pin compatibility enables footprint reuse, but peripheral enablement must be verified per variant datasheet.

What power supply voltages does the DF2280F20BJV support?

The DF2280F20BJV supports both 3.3 V and 5 V single-supply operation, with separate analog and digital power domains (AVCC/AVSS and DVCC/DVSS). This dual-voltage flexibility allows direct interfacing with legacy 5 V sensors and logic, or modern low-power 3.3 V systems. Voltage tolerance and noise isolation specifications ensure stable A/D conversion and I/O signaling across both supply configurations on the DF2280F20BJV.
