Renesas DF2215TUTE24V

Overview

DF2215TUTE24V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2215 Group, featuring the H8S/2000 CPU core, 256 KB on-chip flash memory (F-ZTAT™), 16 KB RAM, and integrated peripherals including USB 1.1, dual SCIs, 16-bit TPU, 8-bit TMR, WDT, 10-bit A/D converter (8 channels), and D/A converter. It operates at up to 24 MHz with 3.3 V supply and targets industrial control and embedded instrumentation.

For engineers reviewing the DF2215TUTE24V datasheet, DF2215TUTE24V pinout, DF2215TUTE24V application, or DF2215TUTE24V equivalent, key selection criteria include its F-ZTAT™ flash reprogrammability, USB interface timing compliance, 24 MHz PLL-supported operation, and wide-temperature support (–40°C to +85°C) for ruggedized embedded deployment.

Technical Context

The DF2215TUTE24V implements the H8S/2000 CPU architecture with sixteen 16-bit general-purpose registers, 32-bit internal data paths, and upward object-level compatibility with H8/300H. Its on-chip system includes a direct memory access controller (DMAC), data transfer controller (DTC), and bus master capability for efficient peripheral-to-memory transfers without CPU intervention.

It integrates a full-speed USB 1.1 controller with dedicated 48-MHz clock generation, two asynchronous serial communication interfaces (SCI0/SCI1) supporting UART and LIN modes, and a 16-bit timer pulse unit (TPU) with input capture, output compare, and PWM generation across six channels - all synchronized to the same 24 MHz main clock domain.

FAQ

What is the maximum operating frequency supported by DF2215TUTE24V?

DF2215TUTE24V supports a maximum system clock frequency of 24 MHz, achieved using its on-chip PLL with 2× or 3× multiplication of an external crystal (e.g., 8 MHz or 12 MHz). This frequency governs CPU execution, peripheral timing, and USB 48-MHz clock derivation. The DF2215TUTE24V datasheet specifies strict setup/hold timing for all I/O at this rate, and operation above 24 MHz violates absolute maximum ratings.

Does DF2215TUTE24V include an integrated USB transceiver?

Yes, DF2215TUTE24V integrates a full-speed USB 1.1 transceiver with differential drivers/receivers for D+ and D– lines, eliminating the need for external PHY components. The DF2215TUTE24V also includes an on-chip 48-MHz clock generator synchronized to the main PLL, meeting USB specification jitter requirements without external oscillators.

What are the analog voltage requirements for using the A/D converter on DF2215TUTE24V?

The DF2215TUTE24V A/D converter requires AVCC = VCC (i.e., identical supply voltage on both pins) to operate correctly. AN0–AN7 inputs are only functional under this condition, as stated in multiple sections of the hardware manual. Using separate analog and digital supplies or mismatched voltages disables the A/D function and may cause undefined behavior in conversion results.

Is DF2215TUTE24V pin-compatible with other members of the H8S/2215 family?

DF2215TUTE24V shares the TFP-120V package and pinout with HD64F2215TU and HD64F2215T, as confirmed in Section 1.3 (Pin Arrangement) and Table 1.5 of the H8S/2215 Hardware Manual. However, mask-ROM variants like HD6432215B differ in pin function mapping for ROM enable/control signals and are not drop-in replacements.

What debug interface does DF2215TUTE24V support for firmware development?

DF2215TUTE24V supports the Renesas E10A-USB and E20 debug interfaces via its on-chip JTAG boundary-scan circuitry (IEEE 1149.1 compliant), with TRST pin (Pin 109) dedicated to TAP controller reset. The DF2215TUTE24V hardware manual specifies mandatory handling of unused JTAG pins and defines timing constraints for debug clock synchronization during programming and real-time tracing.
