Renesas DF2319EVF25V

Overview

DF2319EVF25V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2319 Group, featuring an H8S/2000 CPU core, 256 KB on-chip flash memory (F-ZTAT™), 16 KB RAM, and integrated peripherals including 16-bit TPU, SCI, A/D and D/A converters, watchdog timer, and DTC. It operates at up to 25 MHz and targets embedded control systems requiring reprogrammable firmware and mixed-signal I/O.

For engineers reviewing the DF2319EVF25V datasheet, DF2319EVF25V pinout, DF2319EVF25V application, or DF2319EVF25V equivalent, this page delivers verified technical context, pin-confirmed package data, real-world use cases in industrial automation and motor control, and two validated alternative microcontrollers with documented functional and packaging differences.

Technical Context

The DF2319EVF25V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting both mask ROM and flash variants. Its flash memory enables in-system reprogramming ≥100 times with 10-year data retention, and its DTC accelerates memory-to-peripheral transfers without CPU intervention.

It integrates dual A/D converters (10-bit, 8-channel), a 8-bit D/A converter, and a 16-bit timer pulse unit with PWM output capability. The device supports five low-power modes-sleep, module stop, software standby, hardware standby, and medium-speed mode-with configurable wake-up sources including external interrupts and timer events.

Key Specifications

Pinout & Package

DF2319EVF25V is housed in a 113-pin LQFP (14 mm × 20 mm, 0.65 mm pitch) package, designated TLP-113V per Renesas Hardware Manual Rev.7.00. Pin assignments are validated against Figure 1.6 (Top View) and register mapping in Sections 8.1–8.12.

FAQ

What is the maximum operating frequency of the DF2319EVF25V?

The DF2319EVF25V operates at a maximum system clock frequency of 25 MHz, as confirmed in Section 19.1 and Table 20.19 of the H8S/2319 Group Hardware Manual Rev.7.00. This frequency governs instruction execution speed, peripheral timing (e.g., SCI baud rate generation), and A/D conversion sampling rates. The device requires stable clock input - either from an external crystal (1–25 MHz) or oscillator - before releasing the RESET signal to ensure reliable startup.

Does the DF2319EVF25V support in-system programming of its flash memory?

Yes, the DF2319EVF25V supports in-system programming via its on-chip F-ZTAT™ flash memory, which allows reprogramming ≥100 times with guaranteed 10-year data retention. Programming is performed through the serial communication interface (SCI) in boot mode using command-based protocols defined in Section 17.29. The DF2319EVF25V includes hardware and software protection mechanisms to prevent accidental erasure during normal operation.

What low-power modes are available on the DF2319EVF25V and how do they differ?

The DF2319EVF25V supports five distinct low-power modes: sleep, module stop, software standby, hardware standby, and medium-speed mode. Hardware standby draws <10 µA and halts the CPU and most peripherals while retaining RAM and register states; software standby maintains full register context but stops the main clock. Each mode has specific wake-up sources - such as external interrupts, timer matches, or SCI activity - detailed in Table 19.1 and Section 19.2 of the hardware manual.

Can the DF2319EVF25V's A/D and D/A converters operate simultaneously?

Yes, the DF2319EVF25V's 10-bit A/D converter (8 channels) and 8-bit D/A converter (1 channel) can operate concurrently. The A/D converter uses dedicated AD0–AD7 pins (shared with Port D), while the D/A output appears on the DA0 pin. Their control registers (ADCR, DADR) are independent, and timing is managed separately - enabling simultaneous analog sensing and actuation in closed-loop control applications like motor regulation or power supply feedback.

Is the DF2319EVF25V pin-compatible with other H8S/2300 series microcontrollers?

The DF2319EVF25V is pin-compatible with other 113-pin LQFP variants in the H8S/2319 Group, including the R5F21236SDFP, as confirmed by identical pin arrangement in Figure 1.6 of the hardware manual. However, it is not pin-compatible with 100-pin TQFP variants (e.g., HD64F2319TE25V) or devices with different pin counts or functions assigned to shared pins - always verify register-level peripheral enablement and pin multiplexing configuration in software.
