Technical Context

The UPD70F3358GJ(A)-GAE-AX implements the V850ES CPU core with five-stage pipeline, supporting both little-endian and big-endian data access modes. It features a programmable wait-state generator for external memory interfacing and includes a dedicated DMA controller with 8 channels supporting memory-to-peripheral and peripheral-to-peripheral transfers.

Its clock system integrates a PLL with selectable multiplication factors (×1 to ×8), internal RC oscillator (8 MHz), and external crystal input (1–20 MHz). The device supports three power-saving modes: HALT, STOP, and SLEEP, with wake-up capability from multiple sources including RTC alarm, external interrupt, and serial interface activity.

FAQ

What is the maximum operating frequency of the UPD70F3358GJ(A)-GAE-AX?

The UPD70F3358GJ(A)-GAE-AX operates at a maximum frequency of 32 MHz when using the internal PLL with an external 4 MHz crystal. This yields a 31.25 ns instruction cycle time, enabling hard real-time response for motor control and communication protocols. The device also supports direct external clock input up to 32 MHz, and internal RC oscillator at 8 MHz for low-power initialization sequences. All timing specifications are validated across industrial temperature range (−40°C to +85°C).

Does the UPD70F3358GJ(A)-GAE-AX include a CAN controller?

Yes, the UPD70F3358GJ(A)-GAE-AX integrates one fully compliant CAN 2.0B controller supporting bit rates up to 1 Mbps and 32 message mailboxes with priority-based transmission. It includes built-in error counters, loopback self-test mode, and automatic retransmission on arbitration loss. The CAN module connects directly to external transceivers via dedicated TX/RX pins (P10/P11), and its timing registers allow precise synchronization with ISO 11898-1 physical layer requirements.

What debug interface does the UPD70F3358GJ(A)-GAE-AX support?

The UPD70F3358GJ(A)-GAE-AX supports a standard JTAG interface compliant with IEEE 1149.1, enabling full on-chip debugging with Renesas' MINICUBE2 and E2 emulator tools. It provides real-time trace, hardware breakpoints, watchpoint triggering, and register visibility without halting CPU execution. Debug access remains functional in all low-power modes except STOP, and the interface is electrically isolated from user I/O to prevent interference during development.

How much Flash and RAM does the UPD70F3358GJ(A)-GAE-AX have?

The UPD70F3358GJ(A)-GAE-AX contains 512 KB of on-chip Flash memory with 100,000 write/erase cycle endurance and 48 KB of SRAM. Flash supports in-application programming (IAP) with sector-level erase granularity and code protection lock bits. SRAM is split into two banks (32 KB + 16 KB) with independent power domains, allowing selective retention during low-power modes. Both memories are accessible via the V850ES unified address space with zero-wait-state operation at 32 MHz.

Is the UPD70F3358GJ(A)-GAE-AX pin-compatible with other V850ES/SJ3 devices?

Yes, the UPD70F3358GJ(A)-GAE-AX shares identical 144-pin LQFP pinout and electrical characteristics with other members of the V850ES/SJ3 family, including UPD70F3348(A), UPD70F3368(A), and UPD70F3378(A). This allows drop-in replacement within the same package variant for design flexibility and migration paths-e.g., upgrading to UPD70F3378GJ(A)-GAE-AX adds 256 KB Flash and 16 KB RAM without PCB changes. Pin compatibility covers all I/O, power, clock, reset, and debug signals.
