FAQ
Is UPD70F3939AGJA-GAE-G still in production?
No. Renesas announced end-of-life (EOL) for UPD70F3939AGJA-GAE-G, and production has been discontinued. It is not recommended for new designs. Aetrix Electronics maintains limited legacy stock with full traceability and supports last-time buy programs for ongoing production continuity.
Does UPD70F3939AGJA-GAE-G include a CAN controller?
No. The UPD70F3939AGJA-GAE-G does not integrate a CAN controller. While some V850E/Sx3-H family members include CAN, this specific variant features only the IEBus™ controller and serial interfaces (UART/I²C/SPI). CAN functionality requires external transceivers and software stack implementation.
What is the operating temperature range for UPD70F3939AGJA-GAE-G?
The UPD70F3939AGJA-GAE-G is qualified for operation from −40 °C to +125 °C ambient temperature and meets AEC-Q100 Grade 2 reliability requirements. This rating applies to the full 144-pin LQFP package and all on-chip peripherals including the A/D and D/A converters.
Can UPD70F3939AGJA-GAE-G be used without an external crystal?
Yes. UPD70F3939AGJA-GAE-G supports both external crystal (1–8 MHz) and external clock input modes. Internal RC oscillators are not provided; therefore, a crystal or external clock source is mandatory for system initialization and stable timing operation.
What debug interface does UPD70F3939AGJA-GAE-G support?
UPD70F3939AGJA-GAE-G supports on-chip debugging via the JTAG interface compliant with IEEE 1149.1. Renesas E1/E20 emulators and compatible third-party tools enable full breakpoint, watchpoint, and memory inspection capabilities during development and validation of UPD70F3939AGJA-GAE-G firmware.
