EZ80190AZ050SG

Microprocessors Overview

The Zilog EZ80190AZ050SG is an 8-bit microprocessor based on the eZ80 CPU core, operating at a maximum clock frequency of 50 MHz. It features 8 KB of high-speed data SRAM and supports a supply voltage range of 3.0 V to 3.6 V with 5 V tolerant inputs. The device includes a 16x16-bit Multiply-Accumulator (MACC) with 1 KB dual-port SRAM, four chip selects with individual wait state generators, six counter/timers, and a watchdog timer. Communication interfaces include two Universal Zilog Interface (UZI) channels supporting I2C, SPI, and UART protocols. It provides 32 bits of General-Purpose Input/Output (GPIO), a 2-channel Direct Memory Access (DMA) controller, and fixed-priority vectored interrupts.
