At 24 MHz the core executes most instructions in a single clock cycle, so the throughput is comparable to many 32-bit parts running at lower clock rates when the task is bit-banging or register-level control. ## Analog and connectivity set Nineteen 12-bit ADC channels cover a lot of sensor inputs — thermistors, potentiometers, current shunts — without needing an external mux. The single 10-bit DAC can generate a reference or an analog setpoint. On the digital side, the part speaks I²C, SPI, UART/USART, LIN, and RS-485, so it bridges directly to automotive and industrial buses without a protocol converter.","metaTitle":"Microchip AVR16DD28-E/SS AVR 8-bit MCU, 24 MHz, 16KB Flash","metaDescription":"Microchip AVR16DD28-E/SS 8-bit AVR MCU with 24 MHz core, 16KB Flash, 22 I/O, 19x12b ADC, 1x10b DAC, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"series":"AVR® DD","cpu_core":"AVR","frame_size":"8-Bit","fuse_speed":"24 MHz","connectivity":"I2C, IrDA, LINbus, RS-485, SPI, UART/USART","package_type":"Tube","Number Of I/O":"22","mounting_type":"Surface Mount","product_status":"Active","Data Converters":"A/D 19x12b SAR; D/A 1x10b","Oscillator Type":"External, Internal","lifecycle_stage":"eol_hot","peripheral_types":"Brown-out Detect/Reset, POR, PWM, WDT","supply_voltage_v":"1.8","Program Memory Type":"FLASH","Operating Temperature High":"-40°C to 125°C (TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/52a2acf6540799695f9bd87b1d54ce0d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/AVR16DD28-E%2FSS/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between AVR16DD28-E/SS and AVR32DD28T-I/SS?","answer":"The AVR32DD28T-I/SS also ships in Tape & Reel rather than Tube. If you need the higher Flash density and can accept the 85°C ceiling, it is a drop-in hardware swap; otherwise the 125°C grade of the AVR16DD28-E/SS is the deciding factor."},{"question":"Does the AVR16DD28-E/SS have built-in EEPROM?","answer":"The evidence does not list a separate EEPROM block. The program memory is Flash (16 KB). For nonvolatile parameter storage you would use a Flash sector or an external EEPROM — the I²C/SPI interfaces make that straightforward."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/AVR16DD28-E-SS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/AVR16DD28-E-SS when reusing this data.
