Overview
The AVR64DB32T-I/PT is an 8-bit microcontroller from the AVR DB family, featuring a hardware multiplier CPU running at up to 24 MHz. It includes 64 KB of self-programmable Flash memory, 8 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperatures (-40°C to +85°C). Key peripherals include a 12-bit differential ADC with 13 channels, three op amps, a 10-bit DAC, three zero-cross detectors, and multiple communication interfaces such as USART, SPI, and TWI.
Feature Summary
- Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage level interfacing.
- Includes an Event System for CPU-independent inter-peripheral signaling.
- Provides Configurable Custom Logic (CCL) with programmable Look-up Tables.
- Supports single-pin Unified Program and Debug Interface (UPDI).
Applications
- Analog signal conditioning
- Sensor applications
- IoT terminal nodes
Procurement Notes
Verify the specific ordering suffix 'T' indicates tape and reel packaging and '-I' denotes the industrial temperature range. Confirm package style 'PT' corresponds to TQFP-32. Ensure compatibility with existing design constraints regarding pin count and peripheral availability before finalizing procurement.
Selection Notes
Select this component when 64 KB of Flash and 8 KB of RAM are required in a 32-pin package. It is suitable for designs needing analog features like op amps and ZCDs alongside standard digital interfaces. Consider vertical migration within the AVR DB family if future memory or pin expansion is anticipated without code modification.
Part Context
This part belongs to the AVR64DB28/32/48/64 series, which shares architectural similarities across pin counts. The 'AVR64DB32' designation indicates 64 KB Flash and 32 pins. The 'T' suffix specifies tape and reel carrier type, while 'PT' identifies the TQFP package style.
Replacement Considerations
Devices within the same AVR DB family offer vertical migration options. Check datasheet Table 1 for memory variations and Table 2 for peripheral differences between AVR64DB28, AVR64DB48, and AVR64DB64 variants.
