Product details
Overview
DF2218UTF24WV from Renesas Electronics is a 16-bit flash-based microcontroller (MCU) in the H8S/2218 Group, featuring 128 KB on-chip flash memory, 12 KB RAM, USB boot mode, and integrated peripherals including TPU, WDT, RTC, SCI, A/D converter, and DMAC. It operates at up to 25 MHz and targets embedded control applications requiring real-time responsiveness and peripheral integration.
For engineers reviewing the DF2218UTF24WV datasheet, DF2218UTF24WV pinout, DF2218UTF24WV application, or DF2218UTF24WV equivalent, key selection considerations include USB boot capability, 100-pin TFP package compatibility, boundary-scan debug support (TCK/TMS/TDO/TDI/TRST), and F-ZTAT™ flash reprogrammability for production flexibility.
Technical Context
The DF2218UTF24WV implements the H8S/2000 CPU core with a 32-bit internal architecture, sixteen 16-bit general-purpose registers, and linear 16-Mbyte address space. It supports multiple clock sources including main crystal (EXTAL/XTAL), sub-clock (OSC1/OSC2), and PLL-based system clock generation.
Its on-chip peripheral set includes a 16-bit Timer Pulse Unit (TPU) with 8 channels, a 10-bit A/D converter with 8 input channels, two independent Serial Communication Interfaces (SCI), and USB 1.1-compliant controller with built-in transceiver - all accessible via dedicated I/O ports and configurable interrupt vectors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2218U | Same core, same memory, identical TFP-100GV package - differs only in marking and traceability coding; functionally identical to DF2218UTF24WV | No functional difference; used interchangeably in Renesas documentation and distribution channels | Select HD64F2218U when sourcing from legacy Renesas channel stock or when matching original design BOMs referencing Renesas part numbering |
| R5F22218 | Successor in R8C/22 series with enhanced EMI immunity, lower active current (3.5 mA/MHz), and extended temperature range (−40°C to +105°C) | Requires minor PCB layout revision due to 64-pin LQFP package and different pin mapping; lacks USB PHY but adds LIN interface | Choose R5F22218 for new designs prioritizing power efficiency and automotive-grade reliability where USB is not required |
Compared with DF2218UTF24WV, HD64F2218U offers identical functionality and drop-in compatibility, while R5F22218 provides improved power efficiency and extended temperature tolerance at the cost of USB functionality and requires board-level redesign.

FAQ
What is the primary function of the DF2218UTF24WV in an embedded system?
The DF2218UTF24WV serves as a standalone 16-bit microcontroller executing real-time control tasks, managing on-chip peripherals (TPU, A/D, SCI, USB), and coordinating I/O operations without external support chips. Its integrated USB boot mode and F-ZTAT™ flash make DF2218UTF24WV ideal for field-upgradable industrial devices where firmware maintenance and peripheral integration are critical.
Does the DF2218UTF24WV support JTAG debugging, and which pins are involved?
Yes, the DF2218UTF24WV supports IEEE 1149.1 boundary scan via dedicated JTAG pins: TCK/P76*, TMS/P75*, TDO/P77*, TDI/PG0*, and TRST/NC*. These pins are fully functional in the TFP-100GV package and enable in-circuit debugging, flash programming, and production test without requiring additional interface circuitry - a key capability confirmed in the H8S/2218 Hardware Manual Rev.7.00.
What is the role of the FWE pin on the DF2218UTF24WV?
The FWE (Flash Write Enable) pin is a hardware safety control that must be asserted (driven high) to permit flash memory programming or erase operations on the DF2218UTF24WV. This prevents accidental corruption of firmware during normal operation or noise-induced writes. The DF2218UTF24WV datasheet specifies FWE as active-high and confirms its presence only on flash versions - consistent with HD64F2218 and HD64F2218U variants.
Can the DF2218UTF24WV operate without an external crystal?
No - the DF2218UTF24WV requires an external crystal (or ceramic resonator) connected between EXTAL and XTAL pins to generate the main system clock. While it includes an on-chip PLL for frequency multiplication, the base clock source must be externally provided. The sub-clock oscillator (OSC1/OSC2) is optional and used only for RTC or low-power modes - the DF2218UTF24WV will not execute code without a valid main clock input.
Is the DF2218UTF24WV qualified for automotive applications?
No - the DF2218UTF24WV is rated as a "Standard" quality grade device per Renesas documentation, intended for office equipment, industrial robots, and test instrumentation. It is not qualified for automotive use (which requires "High Quality" grade), lacks AEC-Q100 certification, and does not meet the extended temperature, EMI, or failure-rate requirements for vehicle ECUs. For automotive designs, Renesas recommends the R8C or RH850 families instead of DF2218UTF24WV.
