ZL38012LDF1 [Microchip]

The ZL38012 is a 100 MHz (200 MIPs) Zarlink voice processor with hardware accelerator, featuring dual 8 kHz sampling ΔΣ ADCs and DACs. It supports bootloading for future software upgrades and includes interfaces such as I2S, PCM (TDM/SSI), SPI (master and slave), UART, and GPIO. The device integrates a DSP core, a 2048-tap filter co-processor, and internal memory (3 KB ROM, 27 KB RAM, 24 KB data RAM). It operates at 1.2 V core and 3.3 V I/O with 5 V-tolerant inputs, and is designed for applications requiring acoustic echo cancellation and noise reduction.
