Product details
Overview
UPD70F3015BGC-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 32 MHz. It integrates UART, I²C, 8-bit timers with PWM, 10-bit ADC (8 channels), and operates from 2.7 V to 5.5 V supply. It targets industrial control and embedded instrumentation requiring deterministic real-time response and in-system programmability.
For engineers reviewing the UPD70F3015BGC-8EU-A datasheet, UPD70F3015BGC-8EU-A pinout, UPD70F3015BGC-8EU-A application, or UPD70F3015BGC-8EU-A equivalent, key selection considerations include its V850 ISA compatibility, 80-pin LQFP package, flash self-programming capability, and support for low-power modes including STOP and IDLE.
Technical Context
The UPD70F3015BGC-8EU-A implements the V850 RISC core with 3-stage pipeline execution and supports both little-endian and big-endian data access. Its peripheral set includes a 4-channel 10-bit ADC with sample-and-hold, dual UARTs with FIFO and automatic baud-rate detection, and an I²C interface compliant with standard/fast-mode (up to 400 kHz).
Memory architecture comprises 256 KB on-chip flash (organized as 1 KB sectors), 16 KB SRAM, and 4 KB boot ROM. Power management includes three low-power modes-HALT, STOP, and IDLE-with wake-up via external interrupt, timer, or serial interface event.

FAQ
What is the maximum operating frequency of the UPD70F3015BGC-8EU-A?
The UPD70F3015BGC-8EU-A supports a maximum CPU clock frequency of 32 MHz. This is achieved using an external crystal (1–8 MHz) multiplied by the on-chip PLL. The 32 MHz operation enables sub-microsecond interrupt response and consistent instruction timing critical for real-time control loops in the UPD70F3015BGC-8EU-A.
Does the UPD70F3015BGC-8EU-A support in-system programming of its flash memory?
Yes, the UPD70F3015BGC-8EU-A supports in-system programming (ISP) via its built-in flash controller. It allows sector-based erase (1 KB minimum) and byte/word programming without removing the device from the target board. This capability is essential for field firmware updates and is fully implemented in the UPD70F3015BGC-8EU-A's boot ROM and flash API.
What are the power supply requirements for the UPD70F3015BGC-8EU-A?
The UPD70F3015BGC-8EU-A requires two independent supply domains: VDDD (digital core and I/O) and VDDA (analog peripherals including ADC and PLL). Both accept 2.7 V to 5.5 V, but must be within ±100 mV of each other. Decoupling capacitors (0.1 µF ceramic + 10 µF tantalum) are required per the UPD70F3015BGC-8EU-A hardware manual to ensure stable operation.
How many analog-to-digital converter channels does the UPD70F3015BGC-8EU-A include?
The UPD70F3015BGC-8EU-A integrates an 8-channel, 10-bit successive-approximation ADC. Channels AN0–AN5 map to Port 6 pins (P60–P65), while AN6 and AN7 are dedicated pins. The ADC supports programmable sample-and-hold time, internal reference (1.8 V or 3.0 V), and conversion trigger sources including software, timer, or external event - all confirmed in the UPD70F3015BGC-8EU-A user's manual.
Is the UPD70F3015BGC-8EU-A RoHS-compliant and lead-free?
Yes, the UPD70F3015BGC-8EU-A is a lead-free, RoHS-compliant device. The "-8EU-A" suffix explicitly denotes the 80-pin LQFP package with lead-free finish, as documented in Renesas' U12768EJ4V1UD revision history and ordering information. It meets JEDEC J-STD-020 moisture sensitivity level 3 and requires reflow per the UPD70F3015BGC-8EU-A recommended soldering conditions.
