UPD70F3033BGC-8EU-A

Microcontrollers Overview

The UPD70F3033BGC-8EU-A is a 32-bit microcontroller from the V850/SB1 series, manufactured by Renesas Electronics. It features a 32-bit CPU with an instruction set including signed multiplication and saturation operations. The device integrates 256 KB of flash memory and 16 KB of RAM within a 16 MB linear address space. Key peripherals include multiple serial interfaces (UART, CSI, I2C), a 10-bit A/D converter with 12 channels, DMA controller, and various timers. It operates at a minimum instruction execution time of 50 ns at 20 MHz internal clock.

Microcontrollers Feature Summary

• Integrates flash memory allowing electrical program writing and erasing while mounted on the board.
• Includes a 32-bit CPU core with general-purpose registers and specialized instruction sets for arithmetic and bit manipulation.
• Supports multiple communication protocols via asynchronous and clocked serial interfaces alongside I2C bus capabilities.
• Features power-saving modes such as HALT, IDLE, and STOP to optimize energy consumption.

Microcontrollers Applications

• Audio equipment
• Car audio systems
• Video cassette recorders (VCR)
• Television sets

Microcontrollers Procurement Notes

Verify the specific suffix 'B' in the part number against official Renesas documentation, as standard listings typically reference 'A' or 'AY'. Confirm package type matches the 100-pin LQFP specification. Ensure compliance with export control laws if applicable. Check for any quality grade restrictions regarding 'Specific' applications requiring prior written consent.

Microcontrollers Selection Notes

Select this component for AV equipment requiring onboard programmable memory. Compare with mask ROM versions like the µPD703033A if mass production does not require field updates. Consider the availability of I2C interfaces only in the 'AY' variant if that protocol is critical. Evaluate noise immunity differences between flash and mask ROM versions during system design.

Microcontrollers Part Context

This microcontroller belongs to the V850/SB1 family designed for audio-visual applications. It succeeds earlier mask ROM variants by offering flash memory for easier development and small-scale production. The device maintains compatibility with the broader V850 architecture while providing specific peripheral sets tailored for consumer electronics control tasks.

Microcontrollers Replacement Considerations

The µPD703033A and µPD703033AY are confirmed mask ROM replacements for the flash version in mass production. Ensure identical code is written to empty ROM areas when migrating. Verify pin compatibility and noise immunity characteristics before substituting.
