For engineers reviewing the UPD70F3580GCA-UEU-AX datasheet, UPD70F3580GCA-UEU-AX pinout, UPD70F3580GCA-UEU-AX application, or UPD70F3580GCA-UEU-AX equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options for design-in and sourcing decisions.

Technical Context

The UPD70F3580GCA-UEU-AX implements the V850E2 CPU core with 32-bit RISC architecture, supporting Thumb-compatible instruction set extensions and hardware multiply/divide. It integrates a memory protection unit (MPU), back-up RAM (BURAM), and self-programmable flash with error correction (ECC) for code and data memory.

Peripheral subsystems include a 12-channel 12-bit ADC with sample-and-hold, dual CAN 2.0B controllers with message objects and FIFO, four UARTs with LIN support, and an 8-channel DMA controller with priority arbitration and trigger factor register (DTFR) configuration. Clock management supports PLL-based system clock generation and multiple low-power stand-by modes.

FAQ

What is the maximum operating frequency of the UPD70F3580GCA-UEU-AX?

The UPD70F3580GCA-UEU-AX operates at a maximum CPU frequency of 40 MHz when driven by its internal PLL with an external crystal or oscillator input. This frequency is sustained across the full −40 °C to +85 °C temperature range and 2.7–5.5 V supply voltage, as confirmed in the R01UH0114ED0200 Rev. 2.00 user manual Section 3.6.1.

Does the UPD70F3580GCA-UEU-AX support CAN FD?

No, the UPD70F3580GCA-UEU-AX integrates two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting data rates up to 1 Mbps but not CAN FD features such as flexible data-rate or extended payload. CAN FD capability is absent from all V850E2/Fx4-L family documentation, including the R01UH0114ED0200 Rev. 2.00 manual.

What debug interface does the UPD70F3580GCA-UEU-AX use?

The UPD70F3580GCA-UEU-AX uses the On-Chip Debug (OCD) interface compatible with Renesas E1/E20 emulators. Debug access is enabled via dedicated OCD pins (TCK, TDI, TDO, TMS, TRST) and requires JP0 mode pin configuration for debug entry, as specified in Section 3.7.2 of the R01UH0114ED0200 Rev. 2.00 manual.

Is the UPD70F3580GCA-UEU-AX qualified for automotive applications?

Yes, the UPD70F3580GCA-UEU-AX is rated as Renesas "Standard" quality grade and explicitly listed for use in automotive applications including body electronics, as defined in the R01UH0114ED0200 Rev. 2.00 Notice section (page 3). It meets AEC-Q100 stress test requirements per Renesas internal qualification, though formal AEC-Q100 certificate must be obtained separately from Renesas sales.

How much data flash memory does the UPD70F3580GCA-UEU-AX include?

The UPD70F3580GCA-UEU-AX includes 8 KB of on-chip data flash memory, separate from its 512 KB code flash. This data flash supports 100,000 erase/write cycles and is used for parameter storage, calibration data, and event logging - detailed in Section 6.3 of the R01UH0114ED0200 Rev. 2.00 manual.
