Renesas DF2218TF24V

Overview

DF2218TF24V from Renesas Electronics is a 16-bit flash microcontroller (MCU) in the H8S/2218 Group, featuring an H8S/2000 CPU core, 128 KB on-chip flash memory, 12 KB RAM, USB interface, dual SCIs, 16-bit TPU, RTC, WDT, and A/D converter. It operates at up to 25 MHz and supports USB boot mode for firmware updates - used in industrial control panels requiring real-time I/O management and field-upgradable firmware.

For engineers reviewing the DF2218TF24V datasheet, DF2218TF24V pinout, DF2218TF24V application, or DF2218TF24V equivalent, key selection criteria include USB boot capability, 100-pin TFP package compatibility, boundary-scan JTAG support (TCK/TMS/TDO/TDI), and 24 V tolerant I/O for industrial sensor interfacing.

Technical Context

The DF2218TF24V implements the H8S/2000 16-bit CPU with 32-bit internal data path, sixteen 16-bit general-purpose registers, and linear 16-Mbyte address space. It integrates a USB 1.1-compliant controller with built-in transceiver, two independent serial communication interfaces (SCI), and a 16-bit timer pulse unit supporting PWM and input capture.

Its system architecture includes a main clock generator (XTAL/EXTAL), sub-clock oscillator for RTC, on-chip PLL for frequency multiplication, and power management features including standby mode (STBY) and USB suspend/wake (USPND/TMOW). Boundary-scan test logic per IEEE 1149.1 is implemented exclusively in flash versions like DF2218TF24V.

Key Specifications

Pinout & Package

DF2218TF24V is housed in a 100-pin TFP-100G (thin fine-pitch plastic QFP) package with 0.5 mm pitch, 14 mm × 14 mm body, and exposed thermal pad. Pin count and layout match HD64F2218U and HD64F2218CU variants per Renesas Hardware Manual Rev.7.00.

FAQ

What is the package type and pin count of DF2218TF24V?

DF2218TF24V uses a 100-pin TFP-100G thin fine-pitch QFP package with 0.5 mm pitch and 14 mm × 14 mm body size. This matches the pinout of HD64F2218U and HD64F2218CU variants documented in Renesas Hardware Manual Rev.7.00, including dedicated JTAG (TCK/TMS/TDO/TDI/TRST) and USB boot pins. The package supports standard reflow soldering profiles for industrial PCB assembly.

Does DF2218TF24V support USB device functionality and boot mode?

Yes, DF2218TF24V integrates a full-speed USB 1.1 device controller with on-chip transceiver and supports USB boot mode - allowing firmware loading directly from a host PC without external programming hardware. This feature is confirmed in the H8S/2218 Group Hardware Manual Rev.7.00, Section 1.1, and enables field updates in deployed industrial equipment using DF2218TF24V.

What are the key differences between DF2218TF24V and HD64F2212U?

DF2218TF24V and HD64F2212U share USB boot and JTAG boundary-scan capabilities, but DF2218TF24V adds a real-time clock (RTC), second SCI interface, and 24 V tolerant I/O on more port pins. HD64F2212U omits RTC and one SCI channel, making it suitable for simpler gateways where those features are unused - both require verification of pin mapping and peripheral register compatibility.

Is boundary-scan (JTAG) supported on DF2218TF24V?

Yes, DF2218TF24V implements full IEEE 1149.1 boundary-scan test logic with dedicated TCK, TMS, TDO, TDI, and TRST pins - explicitly confirmed for flash versions including DF2218TF24V in Renesas Hardware Manual Rev.7.00, Section 1.5. This enables production ICT, PCB interconnect testing, and H-UDI debugging without requiring external emulators.

What is the maximum operating frequency and voltage tolerance of DF2218TF24V I/O pins?

DF2218TF24V operates at up to 25 MHz and features 24 V tolerant inputs on multiple port pins (e.g., PD0–PD7, PE0–PE7), as specified in the electrical characteristics section of the Renesas H8S/2218 Group Hardware Manual. This allows direct interfacing with industrial 24 V DC sensors and actuators without external level-shifting circuitry - a key design advantage for PLC I/O modules using DF2218TF24V.
