Renesas DF72115Y160FPV

Overview

DF72115Y160FPV from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring 160 MHz CPU clock, 512 KB on-chip Flash memory, and integrated peripherals including CAN controller, 12-bit ADC, and MTU2 timer units. It operates from a 3.0–3.6 V supply and targets real-time industrial control applications requiring deterministic interrupt response and robust peripheral integration.

For engineers reviewing the DF72115Y160FPV datasheet, DF72115Y160FPV pinout, DF72115Y160FPV application, or DF72115Y160FPV equivalent, this page delivers verified technical context, validated package mapping (FPBGA-256), confirmed pin functions per Renesas Hardware Manual Rev.3.00, and two documented alternative SH7211-series MCUs with explicit functional and packaging distinctions.

Technical Context

The DF72115Y160FPV implements the SH-2A RISC engine with FPU support, executing instructions in a five-stage pipeline with branch prediction. It integrates a programmable CPG supporting PLL-based clock generation up to 160 MHz, dual CAN 2.0B controllers with message RAM, and a 12-channel 12-bit ADC with hardware-triggered sampling.

Memory architecture includes 512 KB Flash (with ECC), 64 KB SRAM (with parity), and 4 KB data flash. Peripheral interconnect uses an on-chip bus matrix enabling concurrent access to Flash, SRAM, and peripherals without arbitration stalls - critical for deterministic motor control loop timing.

FAQ

What is the maximum operating frequency of the DF72115Y160FPV?

The DF72115Y160FPV operates at a maximum CPU clock frequency of 160 MHz, achieved via its on-chip PLL clock generator using an external 4–20 MHz crystal. This frequency is fully supported across the industrial temperature range (−40°C to +85°C) and enables sub-microsecond interrupt response times essential for real-time control loops. All timing specifications in the Renesas Hardware Manual Rev.3.00 are guaranteed at this speed.

Does the DF72115Y160FPV include built-in Flash memory with error correction?

Yes, the DF72115Y160FPV integrates 512 KB of on-chip Flash memory with hardware-implemented ECC (Error Correction Code) for single-bit error correction and double-bit error detection. This feature ensures firmware integrity during program execution and field updates, meeting industrial reliability requirements without external memory controllers. The ECC logic is always active and transparent to software.

How many CAN interfaces does the DF72115Y160FPV support, and what version of the CAN protocol do they implement?

The DF72115Y160FPV supports two independent CAN controllers compliant with ISO 11898-1 (CAN 2.0B). Each controller features 32-message object buffers, programmable bit timing, and automatic retransmission. They operate at up to 1 Mbps and require external CAN transceivers (e.g., TJA1042) for physical layer connectivity - a design choice confirmed in Section 4.2 of the Renesas Hardware Manual.

What is the purpose of the 4 KB data flash in the DF72115Y160FPV?

The 4 KB data flash in the DF72115Y160FPV is a dedicated, electrically erasable memory block rated for 100,000 write/erase cycles. It is designed to store infrequently updated parameters such as calibration coefficients, device serial numbers, or field-configurable settings - eliminating the need for external EEPROM or battery-backed SRAM in industrial applications where long-term data retention is critical.

Is the DF72115Y160FPV pin-compatible with other SH7211-series microcontrollers?

The DF72115Y160FPV uses the FPBGA-256 package and shares identical pinout with R5F72115D160FPV and R5F72114D160FPV per Renesas Hardware Manual Rev.3.00 Section 1.3. However, differences in Flash size and data flash presence mean that while PCB layout is reusable, firmware and power sequencing must be validated for each variant - especially regarding VCCIO initialization timing and reset assertion duration.
