If your control loop or communication protocol needs deterministic instruction execution at a known clock rate, this part delivers one instruction per clock cycle on most single-cycle AVR instructions. At 24 MHz, a tight 100 kHz PWM update or a 1 MHz SPI transaction is comfortably within margin. The 125°C junction maximum is a hard limit — thermal design should keep the die below that under worst-case load, especially with the exposed pad dissipating heat through the PCB. ## 32-VFQFN exposed pad — footprint and thermal checklist The datasheet's recommended land pattern calls for a 3.1x3.1 mm exposed pad on the PCB with at least 9 vias connecting to an internal ground plane. Without that via stitch, junction temperature rises quickly above 85°C ambient. It is ROHS3 compliant. Sourcing through independent distribution is straightforward — we can quote this part against an RFQ with confirmed availability and current pricing at quote time. No last-time-buy risk on this line.","metaTitle":"AVR64DB32-E/RXB 8-bit MCU, 64 KB Flash, 24 MHz","metaDescription":"Microchip AVR64DB32-E/RXB 8-bit AVR MCU with 64 KB Flash, 8 KB RAM, 512 B EEPROM, 24 MHz, 13-ch 12-bit ADC, 1-ch 10-bit DAC, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"AVR® DB","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Microchip Technology","Speed":"24MHz","Series":"AVR® DB","Package":"Tray","RAM Size":"8K x 8","Core Size":"8-Bit","EEPROM Size":"512 x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"AVR","Package / Case":"32-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b; D/A 1x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"AVR64DB32","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"32-VQFN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4800","priceTiers":[{"qty":1,"price":"$2.48000","currency":"USD"},{"qty":25,"price":"$2.26560","currency":"USD"},{"qty":100,"price":"$2.05850","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/AVR64DB32-E%2FRXB/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for the AVR64DB32-E/RXB?","answer":"It is not a pin-compatible drop-in replacement; verify footprint and temperature requirements before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/AVR64DB32-E-RXB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/AVR64DB32-E-RXB when reusing this data.
