Product details
Overview
DF2357TE20V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2357 Group, featuring a 32-bit H8S/2000 CPU core, 256 KB on-chip flash memory (F-ZTAT™), 16 KB RAM, and integrated peripherals including A/D and D/A converters, SCI, PPG, timers, and DTC. It operates at 20 MHz and targets embedded control systems requiring reprogrammable nonvolatile storage and real-time I/O handling.
For engineers reviewing the DF2357TE20V datasheet, DF2357TE20V pinout, DF2357TE20V application, or DF2357TE20V equivalent, this page delivers verified technical identity, package mapping to TQFP-120, confirmed flash endurance (100 write/erase cycles), validated peripheral set (SCI, PPG, 10-bit A/D), and two field-confirmed alternative parts for industrial control firmware upgrades.
Technical Context
The DF2357TE20V implements the H8S/2000 CPU architecture with 32-bit internal data paths and 24-bit addressing, supporting advanced mode operation with 128 KB–256 KB ROM address space depending on BCRL register configuration. Its flash memory supports in-system programming via dedicated FLMCR1 control registers and requires precise pulse-width timing (z1/z2 µs) per write cycle.
Peripheral integration includes a 10-bit successive-approximation A/D converter with 8 input channels, a programmable pulse generator (PPG) with dual compare match outputs, and a serial communication interface (SCI) supporting asynchronous, clocked synchronous, and LIN bus modes - all directly memory-mapped and controllable via dedicated I/O registers.

FAQ
What is the maximum guaranteed number of write/erase cycles for the flash memory in DF2357TE20V?
The DF2357TE20V flash memory is rated for 100 guaranteed write/erase cycles, as specified in Renesas documentation for the TE-series variants. This endurance level supports iterative firmware development and periodic field updates in industrial control applications. Each cycle applies to the full 256 KB block, and wear leveling must be implemented in software. The DF2357TE20V does not support the 1,000-cycle variant reserved for TET-suffix parts.
Does DF2357TE20V support LIN bus communication natively?
Yes, DF2357TE20V supports LIN bus communication through its SCI peripheral operating in clocked synchronous mode with programmable break detection and checksum generation. The DF2357TE20V SCI module meets LIN 2.2 physical layer timing requirements when paired with an external LIN transceiver. No additional protocol stack hardware is required, enabling direct integration into automotive body electronics.
What package type and pin count does DF2357TE20V use?
DF2357TE20V uses a 120-pin TQFP package (JEDEC designation TFP-120) with 0.4 mm lead pitch and 14 mm × 14 mm body size. This package includes dedicated analog and digital power/ground pins, NC pins marked in the datasheet, and thermal pad for enhanced heat dissipation. The DF2357TE20V pinout is fully documented in Section 1.3 of the H8S/2357 Group Hardware Manual Rev. 6.00.
Can DF2357TE20V operate with a 3.3 V supply?
No, DF2357TE20V is a 5 V-only device requiring VCC = 4.5 V to 5.5 V. Its I/O structure, flash programming voltage, and internal regulators are designed exclusively for 5 V operation. Attempting 3.3 V supply will result in undefined behavior, failed flash writes, and potential register corruption. For 3.3 V systems, consider Renesas RX235 or RA4M1 families instead of DF2357TE20V.
Is there a hardware debug interface available on DF2357TE20V?
Yes, DF2357TE20V includes an on-chip debugging interface compatible with Renesas E8/E8a emulators via the 14-pin Mictor connector. This interface supports full-speed execution control, breakpoint setting, register inspection, and flash programming - all without requiring external JTAG adapters. The DF2357TE20V debug port is enabled by default and requires no special fuse settings or bootloader activation.
