Overview
DF2319EVTE25V 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, WDT, 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 DF2319EVTE25V datasheet, DF2319EVTE25V pinout, DF2319EVTE25V application, or DF2319EVTE25V equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and two validated alternative microcontrollers for industrial control, motor drive, and instrumentation designs.
Technical Context
The DF2319EVTE25V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting both mask ROM and flash memory variants. Its flash memory enables ≥100 reprogramming cycles with 10-year data retention and 10–200 ms per 128-byte programming time.
It integrates a 16-bit timer pulse unit (TPU) with input capture/output compare, asynchronous serial communication interface (SCI) with baud rates up to 31.25 kbps at 25 MHz, and 10-bit A/D converter with 8-channel multiplexing and 14.4 µs conversion time. The device supports six operating modes including software standby and module stop for power management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21236SNFP | 16-bit RL78/G13 core, 128 KB flash, 12 KB RAM, lower max clock (24 MHz), integrated LIN transceiver. | Better suited for automotive body electronics with LIN compliance; lacks TPU but adds DMA and more low-power modes. | Select when LIN bus integration and ultra-low power (<0.5 µA) are required over high-speed PWM timing precision. |
| HD64F2319TE25V | Same H8S/2319 Group silicon, identical pinout and peripherals, but uses mask ROM instead of flash memory. | Fixed firmware only; appropriate for high-volume, unchanging applications where field updates are unnecessary. | Choose for cost-sensitive, high-reliability production runs where firmware revision is finalized and flash endurance is not needed. |
Compared with DF2319EVTE25V, R5F21236SNFP trades flash flexibility and TPU precision for automotive-grade LIN support and deeper sleep, while HD64F2319TE25V offers identical functionality with mask ROM-reducing unit cost but eliminating field reprogrammability.

FAQ
What is the maximum operating frequency of the DF2319EVTE25V?
The DF2319EVTE25V operates at a maximum clock frequency of 25 MHz. This rating is specified under standard industrial temperature and voltage conditions (3.0–5.5 V, –40°C to +85°C). The CPU core maintains full functionality and timing compliance at this speed, enabling deterministic execution of real-time control tasks. DF2319EVTE25V supports both crystal and external clock inputs, with oscillator stabilization requirements defined in the hardware manual.
Does the DF2319EVTE25V include on-chip flash memory, and what are its endurance specifications?
Yes, the DF2319EVTE25V integrates 256 KB of F-ZTAT™ flash memory. Its endurance is rated for a minimum of 100 program/erase cycles, with data retention guaranteed for 10 years at 85°C. Programming time is 10–200 ms per 128-byte block, and erase time is 50–1000 ms per block. DF2319EVTE25V supports three protection modes-software, hardware, and error-to prevent unintended writes during operation.
How many analog-to-digital converter (A/D) channels does the DF2319EVTE25V support, and what is its resolution?
The DF2319EVTE25V features a 10-bit successive approximation register (SAR) A/D converter with 8 input channels (AD0–AD7). Conversion time is 14.4 µs at 25 MHz, enabling effective sampling rates up to approximately 69 kHz. Input channels are multiplexed with Port D pins, requiring proper mode configuration prior to conversion. DF2319EVTE25V also includes built-in sample-and-hold and reference voltage selection (AVCC or internal bandgap).
What power management modes are supported by the DF2319EVTE25V?
The DF2319EVTE25V supports six distinct operating modes: high-speed mode, medium-speed mode, sleep mode, module stop mode, software standby mode, and hardware standby mode. Hardware standby draws less than 10 µA, making it suitable for battery-powered applications. Mode transitions are controlled via system control registers and triggered by instructions or external events. DF2319EVTE25V retains RAM contents and selected register states across most low-power modes.
Is the DF2319EVTE25V pin-compatible with other members of the H8S/2319 Group?
Yes, the DF2319EVTE25V shares the same 113-pin LQFP (TLP-113V) package and pin assignment with other H8S/2319 Group variants such as HD64F2319TE25V and HD64F2317SLP. Pin functions-including power, clock, reset, I/O ports, and peripheral signals-are identical across the group. However, differences in on-chip memory type (flash vs. mask ROM) and minor peripheral enablement require verification of firmware and initialization code when substituting variants. DF2319EVTE25V maintains full electrical and mechanical compatibility within the group.
