Product details
Overview
UPD70F3017AYF1-EA6-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 32 MHz. It integrates UART, I²C, 16-bit timer/counters with capture/compare, and 10-bit ADC with 16 channels. It targets industrial control and embedded instrumentation requiring deterministic real-time response and in-system programmability.
For engineers reviewing the UPD70F3017AYF1-EA6-A datasheet, UPD70F3017AYF1-EA6-A pinout, UPD70F3017AYF1-EA6-A application, or UPD70F3017AYF1-EA6-A equivalent, key selection considerations include its V850 ISA compatibility, EA6 package footprint (100-pin LQFP), flash self-programming capability, and support for low-power sleep modes with wake-up via external interrupt or peripheral event.
Technical Context
The UPD70F3017AYF1-EA6-A implements the V850 RISC architecture with 3-stage pipeline execution, supporting both little-endian and big-endian data access. Its memory subsystem includes 256 KB on-chip flash (with 1 KB sector erase granularity) and 16 KB SRAM mapped into unified address space.
Peripheral integration includes a 10-bit successive-approximation ADC with sample-and-hold, four 16-bit general-purpose timers with input capture/output compare/PWM functions, two full-duplex UARTs with framing error detection, and one I²C interface compliant with standard-mode (100 kbps) and fast-mode (400 kbps) specifications.

FAQ
What is the maximum operating frequency of the UPD70F3017AYF1-EA6-A?
The UPD70F3017AYF1-EA6-A operates at a maximum CPU clock frequency of 32 MHz. This is achieved using an external crystal oscillator (1–8 MHz) multiplied by the on-chip PLL. At 32 MHz, the device delivers a minimum instruction execution time of 31.25 ns, enabling tight real-time control loops in applications such as motor drive and sensor signal processing. The UPD70F3017AYF1-EA6-A maintains timing compliance across its specified industrial temperature range (−40°C to +85°C).
Does the UPD70F3017AYF1-EA6-A support in-system programming of its flash memory?
Yes, the UPD70F3017AYF1-EA6-A supports full in-system programming (ISP) of its 256 KB on-chip flash memory via its built-in ROM-resident bootloader. Flash sectors can be erased in 1 KB units and programmed byte-by-byte or word-by-word using standard UART or on-chip debug interface commands. This capability allows field firmware updates without removing the UPD70F3017AYF1-EA6-A from the target board or requiring external programming hardware.
What power-saving modes are available on the UPD70F3017AYF1-EA6-A?
The UPD70F3017AYF1-EA6-A provides four hardware-supported power-saving modes: HALT (CPU stopped, peripherals active), STOP (CPU and most peripherals halted, RAM retained), SLEEP (main clock off, subclock active for RTC/timer wake-up), and DEEP-SLEEP (all clocks off except reset circuit, consuming 1.2 µA typical). Wake-up sources include external interrupts, timer match events, and serial receive activity. These modes make the UPD70F3017AYF1-EA6-A suitable for battery-powered instrumentation.
Is the UPD70F3017AYF1-EA6-A pin-compatible with other V850/SA1 family members?
Yes, the UPD70F3017AYF1-EA6-A uses the EA6 package (100-pin LQFP) and shares identical pin configuration with other V850/SA1 devices in the same package variant, including UPD70F3015AYF1-EA6-A and UPD703017AYF1-EA6-A. Pin functions, power domains, and I/O electrical characteristics are fully aligned across this package group, enabling direct PCB footprint reuse and simplified migration paths within the family.
