FAQ

What is the maximum operating frequency of the UPD70F3017AGC-8EU-A?

The UPD70F3017AGC-8EU-A operates at a maximum CPU clock frequency of 32 MHz. This is achieved using the on-chip PLL with an external crystal (1–20 MHz) or external clock source. The 32 MHz clock drives the V850/SA1 core and all synchronous peripherals, enabling instruction execution at up to 32 million cycles per second with deterministic timing for real-time control loops. The UPD70F3017AGC-8EU-A maintains this frequency across its specified industrial temperature range (−40°C to +85°C) under 3.0–3.6 V supply conditions.

Does the UPD70F3017AGC-8EU-A support in-system programming?

Yes, the UPD70F3017AGC-8EU-A supports full in-system programming via its on-chip bootloader located in 4 KB ROM. This allows field firmware updates using UART or custom protocols without requiring external programming hardware. The 256 KB flash memory is organized into 1 KB erasable sectors, and the UPD70F3017AGC-8EU-A includes dedicated flash control registers and status flags to manage write/erase operations safely during runtime. Self-programming is validated for ≥10,000 erase/write cycles per sector.

What power-saving modes does the UPD70F3017AGC-8EU-A offer?

The UPD70F3017AGC-8EU-A provides four low-power modes: HALT (CPU stopped, peripherals active), STOP (CPU and most peripherals halted, RAM retained), SNOOZE (selected peripherals active, CPU halted), and DEEP STOP (minimal current draw, RAM retention optional). Wake-up from HALT occurs in <10 μs via external interrupt or timer match; STOP mode achieves typical current consumption of 15 μA at 3.3 V. These modes are controlled by the Power Save Control Register (PSC) and are fully documented in the UPD70F3017AGC-8EU-A hardware manual.

Is the UPD70F3017AGC-8EU-A RoHS compliant and lead-free?

Yes, the UPD70F3017AGC-8EU-A is RoHS compliant and manufactured as a lead-free device. The "-8EU-A" suffix explicitly denotes the lead-free, halogen-free 80-pin LQFP package conforming to JEDEC standard J-STD-020 moisture sensitivity level 3. Renesas confirms full compliance with EU Directive 2011/65/EU (RoHS 2) and related regional environmental regulations. The UPD70F3017AGC-8EU-A datasheet specifies reflow soldering profiles compatible with Pb-free assembly processes.

What development tools are supported for the UPD70F3017AGC-8EU-A?

The UPD70F3017AGC-8EU-A is supported by Renesas' legacy V850 toolchain, including the CA850 C compiler (Ver. 2.40+), ID850 integrated debugger, and IE-703017-MC-EM1 in-circuit emulator. Flash programming is enabled via PG-FP3/PG-FP4 programmers or the on-chip UART bootloader. Application notes U13851E and U15673E provide guidance on hardware design and self-programming implementation. The UPD70F3017AGC-8EU-A remains compatible with existing V850/SA1 evaluation boards and debug adapters.
