FAQ

What is the maximum operating frequency of the UPD70F3107AF1-EN4?

The UPD70F3107AF1-EN4 operates at a maximum CPU clock frequency of 32 MHz, supported by its V850E core and on-chip flash memory configured for zero-wait-state access. This frequency is achievable across the full −40°C to +85°C industrial temperature range when supplied with 2.7 V to 5.5 V, and is verified in Renesas' electrical specifications chapter for the V850E/MA1 family. The UPD70F3107AF1-EN4 maintains consistent timing margins under worst-case voltage and temperature conditions.

Does the UPD70F3107AF1-EN4 support in-circuit debugging?

Yes, the UPD70F3107AF1-EN4 includes a standard IEEE 1149.1 JTAG interface that supports full in-circuit emulation, real-time trace, hardware breakpoints, and register/memory inspection without modifying application code. Renesas' IE-V850E-MC emulator and ID850 debugger are fully compatible with the UPD70F3107AF1-EN4, enabling non-intrusive development and validation of time-critical firmware. The UPD70F3107AF1-EN4 reserves dedicated pins for this interface and requires no external debug probe configuration.

What is the flash memory endurance specification for the UPD70F3107AF1-EN4?

The UPD70F3107AF1-EN4 features 512 KB of on-chip flash memory rated for 10,000 write/erase cycles per sector, with 128-byte erase granularity enabling fine-grained firmware updates. This endurance is specified in Renesas' V850E/MA1 Hardware User's Manual (U14359EJ6V0UD) and applies across the full industrial temperature range. The UPD70F3107AF1-EN4 supports in-application programming via its built-in bootloader, allowing field upgrades without removing the device from the system.

How many CAN interfaces does the UPD70F3107AF1-EN4 integrate?

The UPD70F3107AF1-EN4 integrates two independent CAN 2.0B controllers, each supporting bit rates up to 1 Mbit/s and featuring 32 message object buffers with hardware acceptance filtering. These controllers operate concurrently and share no critical resources, enabling true dual-bus operation for redundancy or multi-network topologies. The UPD70F3107AF1-EN4 dedicates separate TX/RX pins for each CAN channel (CAN0 and CAN1), confirmed in its pin configuration documentation.

Is the UPD70F3107AF1-EN4 qualified for automotive applications?

The UPD70F3107AF1-EN4 is classified as a Renesas "Standard" quality grade device, intended for industrial and consumer applications such as office equipment, communications gear, and industrial robots - not for automotive safety-critical systems. While it includes CAN 2.0B and operates across −40°C to +85°C, it lacks AEC-Q100 qualification, automotive-specific failure-in-time (FIT) data, or extended temperature validation beyond the Standard grade scope. For automotive use, Renesas recommends explicitly qualified parts like the R7F701023 or RH850 series. The UPD70F3107AF1-EN4 remains suitable for non-safety automotive body electronics where customer-level validation suffices.
