Product details
Overview
UPD70F3319GC(A)-8EU-QS from Renesas Electronics (formerly NEC Electronics) is a 32-bit RISC V850ES/DG2 System-in-Package microcontroller integrating a V850ES/FE2 CPU core and a dedicated Meter Controller/Driver (MTRC). It delivers 128 KB on-chip ROM, 6 KB RAM, 10-channel 10-bit ADC, 1 CAN channel (ISO 11898-compliant), 4 serial interfaces (2 CSIB + 2 LIN-compatible UARTA), and 60 GPIO pins - all in a 100-pin LQFP package. It is engineered for automotive instrument cluster applications requiring precise stepper motor control.
For engineers reviewing the UPD70F3319GC(A)-8EU-QS datasheet, UPD70F3319GC(A)-8EU-QS pinout, UPD70F3319GC(A)-8EU-QS application, or UPD70F3319GC(A)-8EU-QS equivalent, key selection criteria include its integrated MTRC supporting up to four independent stepper motors, dual-clock domain operation (main clock up to 20 MHz + 32.768 kHz subclock), and automotive-grade temperature range (−40°C to +85°C).
Technical Context
The UPD70F3319GC(A)-8EU-QS implements a Harvard-architecture V850ES CPU with pipeline-optimized instruction execution and compact code density comparable to 16-bit CISC cores. Its SiP architecture tightly couples the V850ES/FE2 core with the MTRC via dedicated CSIB1 serial interface, enabling synchronized motor control without host CPU intervention.
It supports multiple low-power modes - HALT, IDLE1/2, STOP, Sub-clock, and Sub-IDLE - with separate power domains for V850ES/Fx2 logic, analog peripherals (AVDD/AVSS), port I/O (EVDD/EVSS), and MTRC subsystems (MTVDD/MTVSS, SMVDD/SMVSS). The MTRC operates from an internal 8 MHz ring oscillator and provides 28 PWM outputs across four meter channels (SM11–SM44), each configurable for sin+/sin−/cos+/cos− quadrature drive.
