It targets embedded control systems requiring reprogrammability and real-time I/O handling, such as industrial motor controllers and HVAC system supervisors.

For engineers reviewing the DF2319VTE25V datasheet, DF2319VTE25V pinout, DF2319VTE25V application, or DF2319VTE25V equivalent, key selection criteria include flash endurance (≥100 write/erase cycles), 25 MHz max operating frequency, 3.3 V ±10% supply voltage, and support for software standby and module stop power-saving modes.

Technical Context

The DF2319VTE25V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, enabling efficient instruction execution and peripheral access. It integrates a data transfer controller (DTC) for autonomous memory-to-peripheral transfers and a 16-bit timer pulse unit (TPU) with input capture, output compare, and PWM generation capabilities.

Its serial communication interface (SCI) supports asynchronous mode with programmable baud rates up to 31.25 kbps at 25 MHz clock, and the 10-bit A/D converter provides 8-channel sampling with conversion time of 1.2 μs typical. Flash memory programming is performed in-system via command interface using on-chip RAM buffers.

FAQ

What is the maximum operating frequency supported by DF2319VTE25V?

The DF2319VTE25V supports a maximum operating frequency of 25 MHz when supplied with a 3.3 V ±10% power source and using an external crystal or clock input. This frequency defines the upper limit for instruction execution speed, peripheral timing resolution, and real-time response capability in applications such as motor control and sensor data acquisition. The DF2319VTE25V achieves this performance while maintaining compatibility with standard 3.3 V logic families and low-dropout regulators.

Does DF2319VTE25V include on-chip flash memory, and what is its endurance rating?

Yes, DF2319VTE25V integrates 256 KB of on-chip F-ZTAT™ flash memory rated for a minimum of 100 write/erase cycles under specified operating conditions. This allows for in-system firmware updates during development and field deployment without requiring external programming hardware. The DF2319VTE25V uses a command-based programming interface executed from on-chip RAM, supporting both block erase and 128-byte programming operations as documented in the H8S/2319 Group Hardware Manual.

How many analog-to-digital and digital-to-analog converter channels does DF2319VTE25V provide?

The DF2319VTE25V features an 8-channel, 10-bit successive-approximation A/D converter with a typical conversion time of 1.2 μs, and a dual-channel 8-bit D/A converter. These integrated converters eliminate the need for external components in applications requiring analog sensor interfacing and analog output control. The DF2319VTE25V's A/D supports simultaneous sampling across multiple channels via software trigger, while the D/A outputs are accessible through dedicated pins PAG0 and PAG1.

What power-saving modes are available on DF2319VTE25V, and what is the lowest current consumption?

DF2319VTE25V supports five power-saving modes: sleep, module stop, software standby, hardware standby, and deep standby. In software standby mode, current consumption drops to ≤10 μA while retaining RAM and register contents. The DF2319VTE25V exits this mode via external interrupt or reset, enabling rapid resumption of operation-ideal for battery-powered remote sensors or intermittent-control applications requiring extended operational life.

Is DF2319VTE25V pin-compatible with other members of the H8S/2300 Series?

DF2319VTE25V is pin-compatible with other 113-pin LQFP variants in the H8S/2319 Group, including HD64F2319CLP and HD6432317SLP, sharing identical pin assignments for power, ground, reset, clocks, and peripheral I/O. However, it is not pin-compatible with smaller-package variants (e.g., 80-pin) or different subfamilies (e.g., H8S/2200). The DF2319VTE25V maintains full functional and register-level compatibility within its designated variant group, simplifying design reuse across firmware-configurable configurations.
