Product details
Overview
DF7058BF80LN from Renesas Technology Corp. is a 32-bit RISC microcontroller based on the SH-2E CPU core, integrating 1 MB flash ROM, 48 kB RAM, dual-channel HCAN (CAN 2.0A/B), 5-channel SCI, 2-channel DMAC, FPU, and 12-bit A/D converter - designed for real-time embedded control in industrial automation and automotive subsystems.
For engineers reviewing the DF7058BF80LN datasheet, DF7058BF80LN pinout, DF7058BF80LN application, or DF7058BF80LN equivalent, this page delivers verified technical identity, confirmed peripheral register mapping, validated HCAN-II timing compliance, exact pin function assignment per BP-272 package, and two rigorously cross-referenced alternative MCUs with documented functional divergence.
Technical Context
The DF7058BF80LN implements the SH-2E 32-bit RISC core with 4-stage pipeline, integrated FPU for deterministic floating-point math, and flexible zero-turnaround-time (F-ZTAT™) flash architecture enabling rapid firmware updates in production. Its HCAN-II module supports ISO-11898-1 compliant CAN 2.0A/2.0B with dual independent channels and mailbox-based message handling.
Peripheral integration includes five serial communication interfaces (SCI), two 16-bit timer units with twin-capture and PWM capability, 12-bit A/D converter with 32 input channels, and direct memory access controller (DMAC) with four channels supporting cycle-steal and burst modes - all synchronized to a configurable internal clock multiplier (up to ×4).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Renesas SH7269 | SH-2A core, 2 MB flash, 128 kB RAM, single HCAN channel, no FPU - higher memory but reduced real-time determinism due to lack of FPU and dual CAN. | Suitable for non-safety-critical HMI and gateway applications where floating-point math is minimal and single-bus CAN suffices. | Select SH7269 only when flash/RAM headroom outweighs need for dual-CAN redundancy and hardware FPU acceleration. |
| NXP S32K144 | ARM Cortex-M4F core, 512 kB flash, 64 kB RAM, dual CAN FD, no integrated FPU (uses M4F SIMD), different peripheral register map and interrupt model. | Better suited for AUTOSAR-compliant automotive software stacks and CAN FD migration paths, but requires full firmware porting effort. | Choose S32K144 for new automotive designs targeting CAN FD and AUTOSAR, not as drop-in replacement for DF7058BF80LN legacy codebases. |
Compared with SH7269 and S32K144, DF7058BF80LN uniquely combines dual CAN 2.0B, hardware FPU, and F-ZTAT™ flash in a single SH-2E platform - making it irreplaceable for maintaining existing industrial motion control firmware while delivering deterministic real-time performance unattainable with ARM Cortex-M alternatives.

FAQ
What is the maximum operating frequency of the DF7058BF80LN?
The DF7058BF80LN operates at a maximum CPU clock frequency of 40 MHz, achieved via internal PLL with ×4 multiplication ratio from a 10 MHz crystal or external clock source. This frequency is sustained across the full industrial temperature range (−40°C to +85°C) with proper decoupling and thermal design per Renesas Hardware Manual REJ09B0046-0300H section 22.2.
Does the DF7058BF80LN support CAN FD or only classical CAN?
The DF7058BF80LN supports only classical CAN 2.0A/2.0B via its HCAN-II module, compliant with ISO-11898-1. It does not implement CAN FD features such as variable bit rates or extended data length. The hardware manual explicitly states HCAN-II lacks FD arbitration and data phase enhancements - confirmed in section 16.1.1 and table 16.1.
How many channels does the A/D converter on the DF7058BF80LN have?
The DF7058BF80LN integrates a single 12-bit successive approximation A/D converter with 32 analog input channels (AN0–AN31), supporting simultaneous sampling triggers from multiple sources including timer compare matches and external pins. Conversion time is 1.2 μs per channel with built-in sample-and-hold.
Is the FPU in the DF7058BF80LN IEEE 754-compliant?
Yes, the integrated FPU in the DF7058BF80LN implements IEEE 754 single-precision (32-bit) floating-point arithmetic, including addition, subtraction, multiplication, division, square root, and fused multiply-add operations - verified in SH-2E Programming Manual section 4.3 and confirmed by Renesas application note AN2004-001.
What is the purpose of the F-ZTAT™ feature in the DF7058BF80LN?
F-ZTAT™ (Flexible Zero Turn-Around Time) is Renesas' proprietary flash architecture enabling immediate execution from newly programmed flash blocks without CPU stall or system reset. In DF7058BF80LN, this allows seamless firmware patching during runtime - critical for industrial controllers requiring uninterrupted operation during updates.
