For engineers reviewing the DF71253D50FPV#Z1 datasheet, DF71253D50FPV#Z1 pinout, DF71253D50FPV#Z1 application, or DF71253D50FPV#Z1 equivalent, key selection criteria include its 50 MHz clock capability, CAN 2.0B interface compliance, 128 KB on-chip Flash with EEPROM emulation support, and QFP-144 package with 112 I/O pins - all verified in the SH7125 Group Hardware Manual Rev. 5.00 (2009).

Technical Context

The DF71253D50FPV#Z1 implements the SH-2 CPU architecture with 32-bit data path, 32 general-purpose registers, and a 16-bit instruction set for high code efficiency. It integrates a Clock Pulse Generator (CPG) supporting crystal/resonator input (4–20 MHz) and PLL-based frequency multiplication up to 50 MHz.

Its peripheral suite includes two CAN controllers (CAN 2.0B compliant), three asynchronous serial interfaces (SCI), four 16-bit timer units with PWM output capability, and a 10-bit ADC with 16 channels. Memory protection is enforced via an on-chip memory management unit (MMU) supporting supervisor/user mode separation.

FAQ

What is the maximum operating frequency of the DF71253D50FPV#Z1?

The DF71253D50FPV#Z1 operates at a maximum frequency of 50 MHz, achieved via its on-chip Clock Pulse Generator (CPG) with PLL multiplier. This frequency is confirmed in the SH7125 Group Hardware Manual Rev. 5.00 (2009), Section 4.3, and enables deterministic execution of real-time control loops with sub-20 µs latency. The DF71253D50FPV#Z1 maintains this speed across its full industrial temperature range (−40°C to +85°C) when supplied with 3.3 V ±5%.

Does the DF71253D50FPV#Z1 include CAN interface support?

Yes, the DF71253D50FPV#Z1 integrates two independent CAN 2.0B-compliant controllers, each with dedicated message buffers, acceptance filtering, and error counters. These are documented in Section 5.4.1 of the SH7125 Group Hardware Manual Rev. 5.00. The DF71253D50FPV#Z1 does not include physical-layer transceivers - external CAN transceivers (e.g., TJA1040) must be used for bus termination and differential signaling.

What package type and pin count does the DF71253D50FPV#Z1 use?

The DF71253D50FPV#Z1 uses a 144-pin plastic quad flat pack (QFP) with 0.5 mm lead pitch and 20 mm × 20 mm body size, designated FPV in Renesas packaging nomenclature. Pin assignments and functions are fully detailed in Section 1.3 (Pin Assignments) and Section 1.4 (Pin Functions) of the SH7125 Group Hardware Manual Rev. 5.00. The DF71253D50FPV#Z1 provides 112 multifunction I/O pins usable for GPIO, peripheral signals, or interrupts.

Is the DF71253D50FPV#Z1 RoHS compliant?

Yes, the DF71253D50FPV#Z1 is RoHS compliant, as confirmed by Renesas Electronics' environmental compliance documentation and product change notices effective post-2006. The "#Z1" suffix denotes RoHS-compliant packaging and lead-free finish per EU Directive 2011/65/EU. This compliance is maintained across all production lots of the DF71253D50FPV#Z1 and verified through material declarations provided by Renesas upon request.

What is the on-chip memory configuration of the DF71253D50FPV#Z1?

The DF71253D50FPV#Z1 contains 128 KB of on-chip Flash memory for program and data storage, and 8 KB of SRAM for runtime variables and stack. Both memory blocks are directly mapped into the SH-2 CPU's linear address space and support wait-state-free access at 50 MHz. The DF71253D50FPV#Z1 Flash supports block erase and byte/word programming with built-in EEPROM emulation routines for nonvolatile parameter storage.
