FAQ
What is the maximum operating frequency of the UPD70F3724GJ(R)-UEN-A?
The UPD70F3724GJ(R)-UEN-A operates at a maximum system clock frequency of 32 MHz. This frequency is supported across its full industrial temperature range (-40°C to +85°C) and supply voltage range (2.7 V to 3.6 V). The V850ES CPU core executes most instructions in a single cycle at this speed, enabling deterministic real-time response critical for motor control and industrial automation applications. The UPD70F3724GJ(R)-UEN-A achieves this performance without requiring external clock multiplication.
Does the UPD70F3724GJ(R)-UEN-A support CAN FD or only classical CAN?
The UPD70F3724GJ(R)-UEN-A integrates a CAN 2.0B controller compliant with ISO 11898-1:2003 and supports only classical CAN (up to 1 Mbps), not CAN FD. Its hardware message object RAM, bit timing configuration registers, and acceptance filtering logic are designed exclusively for CAN 2.0B frame formats. For CAN FD requirements, designers should consider newer Renesas families such as RA6Mx or RH850. The UPD70F3724GJ(R)-UEN-A remains fully functional in legacy CAN networks deployed in industrial machinery and building systems.
What debug interfaces are supported by the UPD70F3724GJ(R)-UEN-A?
The UPD70F3724GJ(R)-UEN-A supports on-chip debugging via the dedicated NMI/DBG pin and associated debug control logic compliant with Renesas' standard debug protocol. It is fully compatible with MINICUBE2 and IECUBE in-circuit emulators, enabling non-intrusive breakpoints, register inspection, and real-time trace. No external JTAG adapter is required - the UPD70F3724GJ(R)-UEN-A uses a proprietary 4-wire debug interface that shares pins with normal I/O functions, minimizing footprint impact. Debug firmware resides entirely within the UPD70F3724GJ(R)-UEN-A's on-chip ROM.
Is the UPD70F3724GJ(R)-UEN-A qualified for automotive applications?
No, the UPD70F3724GJ(R)-UEN-A is classified as a "Standard" quality grade device per Renesas documentation and is intended for industrial applications such as motor control, factory automation, and building systems - not automotive use. It does not meet AEC-Q100 stress test requirements or possess automotive-specific qualification (e.g., PPAP, IATF 16949 traceability). While functionally capable of operating in vehicle environments, Renesas explicitly restricts its use to non-safety-critical industrial contexts unless formally approved under special agreement. Automotive-grade alternatives include RH850/F1L or RL78/F14 series.
What is the Flash endurance specification for the UPD70F3724GJ(R)-UEN-A?
The UPD70F3724GJ(R)-UEN-A specifies 100,000 write/erase cycles for its 512 KB on-chip Flash memory, with guaranteed data retention of 20 years at 85°C. This endurance rating applies to the entire Flash array and is validated under standard operating conditions (2.7–3.6 V, -40°C to +85°C). Sector erase and byte-programming operations are supported, and Flash programming is performed in-system via the on-chip debug interface without requiring high-voltage VPP. The UPD70F3724GJ(R)-UEN-A also includes Flash protection registers to prevent accidental overwrite of critical firmware sections.
