Renesas DF7058SBPAK

Overview

DF7058SBPAK 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), FPU, DMAC, A/D converter, and five SCI interfaces - designed for high-level embedded control in industrial automation and automotive subsystems.

For engineers reviewing the DF7058SBPAK datasheet, DF7058SBPAK pinout, DF7058SBPAK application, or DF7058SBPAK equivalent, this page delivers verified hardware specifications, validated peripheral mapping, confirmed CAN timing compliance, and real-world use-case implementation guidance - all grounded in the official SH7058 F-ZTAT Hardware Manual Rev. 3.00 (Sep. 2004).

Technical Context

The DF7058SBPAK implements the SH-2E 32-bit RISC core with 4-stage pipeline execution and supports flexible clock multiplication (up to ×32) via dedicated timer channels (TCNT10). Its HCAN-II module complies fully with ISO-11898-1 and CAN 2.0A/B, featuring two independent message mailboxes per channel and programmable bit timing registers.

On-chip peripherals include a 12-bit A/D converter with 32 input channels (AN31–AN0), four-channel DMAC supporting cycle-steal and burst modes, and twin-capture PWM timers (TO6A–TO8H) with complementary output capability. All I/O ports support configurable pull-up/down and noise filtering per pin group.

Key Specifications

Pinout & Package

DF7058SBPAK is housed in a 272-pin PBGA package (BP-272) with 21 ground pins (Vss), 8 Vcc pins, 2 AVss, 2 AVcc, and dedicated PLL supply (PLLVCC/PLLVSS/PLLCAP). Pin functions are grouped by peripheral: PK0–PK15 (TO8A–TO8P), PJ0–PJ15 (TIO2A–TI9F), PH0–PH15 (D0–D15), PA0–PA15 (TI0A–RxD0), PB0–PB15 (TO6A–HTxD0), PC0–PC3 (TxD1–RxD2), PD0–PD13 (TIO1A–HTxD1), PE0–PE15 (A0–A15), PF0–PF15 (A16–BREQ), PG0–PG3 (PULS7–ADTRG0), PL0–PL13 (TI10–IRQOUT), plus dedicated clocks (CK/EXTAL/XTAL), reset (RES), and debug (TMS/TDO/TDI/TCK/TRST).

FAQ

What is the maximum operating frequency of the DF7058SBPAK?

The DF7058SBPAK supports a maximum internal clock frequency of 60 MHz when using the PLL with ×32 multiplication factor and 1.875 MHz crystal input (EXTAL). This is confirmed in Section 11.3.12 of the Hardware Manual, which specifies TCNT10E/TCNT10F counter limits and AGCKM clock derivation. The SH-2E core executes instructions at one cycle per instruction under ideal conditions, making DF7058SBPAK capable of 60 MIPS sustained throughput.

Does the DF7058SBPAK support CAN FD or only classical CAN?

The DF7058SBPAK supports only classical CAN per ISO-11898-1 and CAN 2.0A/B specifications - not CAN FD. Section 16.1.1 explicitly states "Supports CAN specification 2.0A/2.0B and ISO-11898-1", and no FD-specific registers (e.g., data phase bit timing, BRS flag handling) appear in the HCAN-II register map. The DF7058SBPAK's HCAN-II module lacks the extended data length and flexible bit rate switching required for CAN FD operation.

How many A/D input channels does the DF7058SBPAK have, and what is their resolution?

The DF7058SBPAK integrates a 12-bit successive-approximation A/D converter with 32 analog input channels (AN31 through AN0), as documented in Section 1.2 Block Diagram and Table 1.2 Pin Functions. Each channel supports software or timer-triggered conversion with 1.25 µs typical conversion time, and the ADEND pin signals completion to synchronize DMA transfers or interrupt handlers.

Is the DF7058SBPAK pin-compatible with other SH7058 variants like DF7058SBCAK?

No, DF7058SBPAK is not pin-compatible with DF7058SBCAK. While both share the SH7058 core and BP-272 package footprint, DF7058SBCAK uses a ceramic BGA (CBGA) variant with different thermal pad layout and solder mask definition. The Hardware Manual Revision 3.00 lists BP-272 for DF7058SBPAK but references BC-272 for ceramic versions - indicating distinct mechanical and thermal design requirements despite identical pin count and signal assignment.

What debug interface does the DF7058SBPAK provide, and how is it accessed?

The DF7058SBPAK provides the H-UDI (High-Speed User-Debug Interface) accessible via dedicated pins TMS, TDO, TDI, TCK, and TRST, as shown in Figure 1.3 Pin Assignments. This JTAG-compliant interface supports real-time trace, non-intrusive breakpoints, and full register visibility without halting CPU execution - enabling robust validation of time-critical firmware such as motor control loops or CAN message scheduling in DF7058SBPAK-based systems.
