Renesas DF2319CVLP25V

Overview

DF2319CVLP25V 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 interfacing.

For engineers reviewing the DF2319CVLP25V datasheet, DF2319CVLP25V pinout, DF2319CVLP25V application, or DF2319CVLP25V equivalent, key selection considerations include its 113-pin LQFP package, 25 MHz max clock frequency, flash endurance of ≥100 write/erase cycles, and support for software standby and module stop power modes.

Technical Context

The DF2319CVLP25V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, enabling high-level control tasks while maintaining code efficiency. Its peripheral set includes a 16-bit timer pulse unit with input capture/output compare, asynchronous serial communication interface (SCI) supporting bit rates up to 31.25 kbps at 25 MHz, and a 10-bit A/D converter with 8 channels and 1.2 μs conversion time.

It supports multiple low-power operating modes-software standby, module stop, and hardware standby-with retention of register and I/O states in software standby mode. Flash programming is performed via on-chip command interface in user program or boot mode, with block erase capability and checksum error detection during 128-byte programming operations.

FAQ

What is the maximum operating frequency of the DF2319CVLP25V?

The DF2319CVLP25V supports a maximum system clock frequency of 25 MHz, achieved using an external crystal oscillator or clock source connected to the EXTAL/XTAL pins. This frequency defines the upper limit for instruction execution speed, peripheral timing, and A/D conversion rate. The DF2319CVLP25V maintains electrical specifications and timing compliance across its full operating temperature range when run at this rated speed.

Does the DF2319CVLP25V include on-chip flash memory, and what is its endurance rating?

Yes, the DF2319CVLP25V integrates 256 KB of on-chip F-ZTAT™ flash memory. Its specified endurance is a minimum of 100 write/erase cycles per block, as confirmed in Renesas' Hardware Manual Rev.7.00. This allows for limited field firmware updates during product deployment. The DF2319CVLP25V supports in-system programming via its built-in command interface without requiring external programmers or UV erasure.

How many analog-to-digital input channels does the DF2319CVLP25V support, and what is its resolution?

The DF2319CVLP25V features a 10-bit successive-approximation A/D converter with 8 input channels, as documented in Section 14 of the Hardware Manual. Conversion time is 1.2 μs under standard conditions, enabling sampling rates up to approximately 833 kSPS for single-channel operation. The DF2319CVLP25V supports both software-triggered and timer-triggered conversions, making it suitable for synchronized sensor acquisition in control loops.

What low-power operating modes are available on the DF2319CVLP25V, and which retain RAM contents?

The DF2319CVLP25V supports five low-power modes: high-speed, medium-speed, sleep, module stop, and hardware standby. Software standby mode retains all register and RAM contents while reducing current draw significantly. In contrast, hardware standby halts the CPU and most peripherals but preserves only critical state; RAM retention depends on VCC stability. The DF2319CVLP25V documentation confirms that software standby maintains full 16 KB RAM integrity during extended idle periods.

Is the DF2319CVLP25V pin-compatible with other members of the H8S/2319 Group, such as the HD64F2319CLP?

Yes, the DF2319CVLP25V shares identical pinout and package (113-pin LQFP) with other members of the H8S/2319 Group, including the HD64F2319CLP. This enables direct substitution in existing designs when migrating between flash and mask ROM variants or different speed grades. All I/O, power, clock, and reset pin assignments match exactly, and the DF2319CVLP25V maintains full register-level compatibility with the group's peripheral configuration model.
