The ATUC256L4U-D3HT is a 32-bit AVR microcontroller by Microchip Technology, based on the AVR32 CPU core. It delivers up to 64 DMIPS at 50MHz from Flash with one wait state, and up to 36 DMIPS at 25MHz with zero wait state.
The device integrates 256KB of Flash memory with single-cycle access up to 25MHz and 32KB of SRAM. Peripheral features include 12 DMA channels, a 12-bit ADC with 8 channels, 6 timer/counters, 36 PWM channels, and multiple serial interfaces: 4 USART, 1 SPI, and 4 I2C-compatible TWI interfaces. It also supports full-speed and low-speed USB device operation.
The microcontroller is housed in a 48-UFLGA exposed pad package (supplier package 48-TLLGA, 5.5x5.5mm) for surface-mount assembly. It operates from a supply voltage of 1.62V to 3.6V and across a temperature range of -40°C to +85°C. Additional integrated peripherals include brown-out detect, DMA, power-on reset, PWM, and a watchdog timer.
The supply voltage range is 1.62V to 3.6V.
It is available in a 48-UFLGA Exposed Pad package, with supplier package 48-TLLGA (5.5x5.5mm) for surface mount.
The operating temperature range is -40°C to +85°C (TA).
RoHS compliance is listed as RoHS3 Compliant, but this status is unverified.
The maximum clock speed is 50MHz from Flash with one wait state, delivering up to 64 DMIPS.
It has 256KB of Flash memory and 32KB of SRAM.
It supports I2C, SPI, UART/USART, and USB (full speed and low speed device).
