Renesas UPD70F3017AYGC-8EU-A

Overview

UPD70F3017AYGC-8EU-A from Renesas Electronics is a 32-bit V850/SA1 single-chip microcontroller featuring 256 KB on-chip flash memory, 16 KB RAM, and a maximum CPU clock of 33 MHz. It integrates UART, I²C, 16-bit timers with capture/compare, 10-bit ADC (8 channels), and operates from 2.7 V to 5.5 V supply. It is used in industrial control panels requiring deterministic real-time response and firmware-upgradable logic.

For engineers reviewing the UPD70F3017AYGC-8EU-A datasheet, UPD70F3017AYGC-8EU-A pinout, UPD70F3017AYGC-8EU-A application, or UPD70F3017AYGC-8EU-A equivalent, key selection criteria include flash endurance (10,000 erase/write cycles), operating temperature range (–40°C to +85°C), and compatibility with Renesas' FA-100GC-8EU flash programming adapter.

Technical Context

The UPD70F3017AYGC-8EU-A implements the V850E core architecture with 3-stage pipeline execution and supports both little-endian and big-endian data ordering via software configuration. Its peripheral set includes a bus control unit (BCU) for external memory expansion up to 4 MB, and a dedicated DMA controller supporting memory-to-peripheral and peripheral-to-memory transfers without CPU intervention.

Power management includes four operating modes - normal, stop, sleep, and subclock - with wake-up capability from all low-power states via external interrupt or internal timer. The on-chip clock generator supports main clock (up to 33 MHz crystal or external source), subclock (32.768 kHz), and PLL-based frequency multiplication.

FAQ

What is the maximum operating frequency of the UPD70F3017AYGC-8EU-A?

The UPD70F3017AYGC-8EU-A supports a maximum CPU clock frequency of 33 MHz. This is achieved using either an external crystal oscillator (1–33 MHz), an external clock source, or an internal PLL that multiplies the main clock. The device maintains full functionality-including flash read/write and peripheral operation-at this rated speed, with zero wait states for on-chip SRAM access.

Does the UPD70F3017AYGC-8EU-A support in-system programming of its flash memory?

Yes, the UPD70F3017AYGC-8EU-A supports in-system programming via its built-in self-programming capability. Firmware updates can be performed through the UART interface using Renesas' standard bootloader protocol, or via dedicated hardware adapters such as the FA-100GC-8EU. No external programmer is required, and flash erase/write operations are managed entirely by on-chip firmware routines.

What is the ADC resolution and channel count on the UPD70F3017AYGC-8EU-A?

The UPD70F3017AYGC-8EU-A integrates a 10-bit successive approximation ADC with 8 input channels. These channels are multiplexed onto Port 6 pins (P60–P67) and support programmable sample-and-hold timing, scan mode for sequential conversion, and hardware trigger synchronization with timers. Conversion time is typically 10 µs per channel under standard conditions.

Is the UPD70F3017AYGC-8EU-A RoHS-compliant and lead-free?

Yes, the UPD70F3017AYGC-8EU-A is a lead-free, RoHS-compliant device. Its packaging uses matte tin plating on the 80-pin LQFP leads and conforms to JEDEC J-STD-020 moisture sensitivity level 3. The part marking "-8EU-A" explicitly denotes the lead-free, industrial-grade variant per Renesas' ordering nomenclature.

What debug and emulation tools are compatible with the UPD70F3017AYGC-8EU-A?

The UPD70F3017AYGC-8EU-A is fully supported by Renesas' IE-703017-MC in-circuit emulator and the ID850 integrated debugger. Its on-chip debug module implements the standard V850 debug interface, enabling non-intrusive breakpoints, real-time register/memory inspection, and trace buffer capture. Development toolchains including CA850 C compiler and SM850 simulator also target this device.
