The 28-pin SPDIP package is through-hole, so it's socket-friendly for prototyping and field-repairable without hot air. ## Analog peripherals — 9-channel ADC and a DAC on-chip ## Connectivity and I/O count for control applications With 21 I/O lines and I²C, SPI, and UART/USART serial interfaces, this MCU can talk to common sensors, displays, and actuators over a bus. The 24 MHz clock gives enough headroom for 8-bit control loops and communication protocol handling in motor drives, industrial sensor nodes, or HVAC controllers. ## Active production — no end-of-life clock ticking It's ROHS3 compliant.","metaTitle":"Microchip AVR32DB28-E/SP 8-bit MCU, 24 MHz, 32 KB Flash","metaDescription":"AVR32DB28-E/SP is an 8-bit AVR MCU with 24 MHz core, 32 KB Flash, 4 KB RAM, 512 B EEPROM, 9x12-bit ADC, 1x10-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":{"Speed":"24MHz","Series":"AVR® DB","Package":"Tube","RAM Size":"4K 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":"Through Hole","Number of I/O":"21","Core Processor":"AVR","Package / Case":"28-DIP (0.300\\\", 7.62mm)","Data Converters":"A/D 9x12b; D/A 1x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"28-SPDIP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.32","priceTiers":[{"qty":1,"price":"$3.32000","currency":"USD"},{"qty":25,"price":"$3.04760","currency":"USD"},{"qty":100,"price":"$2.76000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/AVR32DB28-E%2FSP/alternatives.json"},"ai":{"faq":[{"question":"What are alternatives to AVR32DB28-E/SP?","answer":"The AVR32DD28T-I/SS is a surface-mount sibling in the AVR DD series with 22 I/O and a 19-channel 12-bit ADC, but it operates only to 85°C and comes in an SSOP package. The PIC16LF1559-I/SS from Microchip's PIC family runs at 32 MHz with 17 I/O and a 10-bit ADC, also limited to 85°C.
