FAQ
What is the maximum operating frequency of the DF7058BF80KN?
The DF7058BF80KN operates at a maximum internal CPU frequency of 80 MHz, achieved via PLL multiplication of an external 4–20 MHz crystal connected to EXTAL/XTAL pins. This frequency is sustained across industrial temperature range (−40°C to +85°C) with appropriate decoupling and voltage regulation per the hardware manual section 12.1.4.
Does the DF7058BF80KN support CAN FD?
No, the DF7058BF80KN implements HCAN II compliant only with CAN 2.0A/2.0B protocols and ISO-11898-1 physical layer - it does not support CAN FD data rates or extended frame formats. Its dual HCAN controllers operate at up to 1 Mbps with standard 11-bit or 29-bit identifiers, as confirmed in section 16.1.1 of the hardware manual.
How many A/D converter channels does the DF7058BF80KN provide?
The DF7058BF80KN integrates a 12-bit successive-approximation A/D converter with 32 multiplexed analog input channels (AN31–AN0), supporting simultaneous sampling triggers from multiple timer units and software start modes. Conversion time is guaranteed at ≤1.2 μs per channel under rated Vcc and temperature conditions.
Is the DF7058BF80KN pin-compatible with other SH7058 variants?
Yes, DF7058BF80KN shares identical BP-272 pinout and electrical characteristics with other SH7058 F-ZTAT™ variants (e.g., DF7058AF80KN, DF7058CF80KN), differing only in flash configuration and factory-programmed options. Pin assignments, power domains, and peripheral mappings are fully consistent per Table 1.3 in the hardware manual Rev. 3.00.
What debug interface does the DF7058BF80KN support?
The DF7058BF80KN supports the H-UDI (Hitachi User Debug Interface) standard via dedicated TMS, TRST, TDI, TDO, and TCK pins, enabling full-speed real-time debugging, breakpoint insertion, and memory inspection using Renesas E1/E20 emulators and High-performance Embedded Workshop IDE.
