Renesas DF7058BP80KNV

Overview

DF7058BP80KNV from Renesas Technology Corp. is a 32-bit RISC microcontroller based on the SH-2E CPU core, featuring 1 MB flash ROM, 48 kB RAM, integrated FPU, dual-channel HCAN II (CAN 2.0A/B compliant), 5-channel SCI, 4-channel DMAC, and 12-bit A/D converter - deployed in industrial motion control systems requiring real-time deterministic response.

For engineers reviewing the DF7058BP80KNV datasheet, DF7058BP80KNV pinout, DF7058BP80KNV application, or DF7058BP80KNV equivalent, key selection considerations include flash-based F-ZTAT™ flexibility for rapid firmware iteration, HCAN II dual-channel bus arbitration support, and peripheral integration reducing external component count in embedded control designs.

Technical Context

The DF7058BP80KNV implements the SH-2E 32-bit RISC architecture with 16-stage pipeline execution, supporting integer and floating-point arithmetic via on-chip FPU. It integrates a flexible clock generator with PLL, enabling configurable system clocks up to 80 MHz.

Its HCAN II module complies fully with ISO 11898-1 and CAN 2.0A/B specifications, providing two independent CAN controllers with mailbox-based message handling, programmable bit timing, and error detection - but excludes timestamp capture, TTE, DART, and timer-triggered transmission functions per hardware manual Rev. 3.00.

FAQ

What is the maximum operating frequency of the DF7058BP80KNV?

The DF7058BP80KNV supports a maximum system clock frequency of 80 MHz, achieved via its on-chip PLL with external crystal input (XTAL/EXTAL). This enables sustained instruction throughput exceeding 100 MIPS for real-time control tasks. The SH-2E core's 16-stage pipeline and integrated FPU ensure deterministic execution timing critical for motor control loops. DF7058BP80KNV maintains stability across its specified industrial temperature range (-40°C to +85°C) at this frequency.

Does the DF7058BP80KNV support CAN FD?

No, the DF7058BP80KNV implements HCAN II modules compliant only with CAN 2.0A and 2.0B specifications (ISO 11898-1), not CAN FD. Its bit-rate is limited to 1 Mbps maximum, and it lacks the variable data-length and fast-bit-rate phases defined in CAN FD. For CAN FD support, Renesas recommends successor devices such as the R5F70D582DFP or SH7269R. DF7058BP80KNV remains ideal for established CAN 2.0 networks in industrial automation where protocol extension is unnecessary.

What package type is used for the DF7058BP80KNV?

The DF7058BP80KNV is packaged in a 272-pin plastic ball grid array (BP-272) with 1.0 mm pitch. This BGA configuration provides high I/O density, excellent thermal performance, and signal integrity for high-speed bus interfaces like external memory and CAN transceivers. The BP-272 footprint is documented in Section 1.3.1 of the SH7058 Hardware Manual (Rev. 3.00) and requires controlled-depth reflow profiling for reliable assembly. DF7058BP80KNV does not offer LQFP or QFP alternatives.

Can the DF7058BP80KNV perform simultaneous analog-to-digital conversions?

Yes, the DF7058BP80KNV's 12-bit A/D converter supports simultaneous sampling across multiple channels using its internal trigger sources (e.g., timer compare match or external ADTRG signal). It features 32 input channels multiplexed through a single ADC core, with conversion times as low as 1.2 μs per sample. The DMAC can autonomously transfer results to memory without CPU intervention. DF7058BP80KNV's dual-sample-and-hold capability enables synchronized current/voltage acquisition essential for three-phase motor control algorithms.

Is the DF7058BP80KNV pin-compatible with other SH7058 variants?

No, DF7058BP80KNV is not pin-compatible with other SH7058 variants such as the DF7058FP or DF7058BP60KNV due to differences in speed grade, voltage rating, and package-specific ball assignments. While all SH7058 devices share the BP-272 mechanical outline, electrical pin functions and timing parameters vary - for example, DF7058BP80KNV is rated for 80 MHz operation at 3.3 V, whereas lower-speed variants may have different drive strength or slew rate specifications. DF7058BP80KNV requires validation against its specific datasheet and hardware manual.
