Z8S18033VEC00TR

Overview

The Z8S18033VEC00TR is a microprocessor based on the Z80 core, operating at a maximum clock frequency of 33 MHz. It features an 8-bit data bus width and supports up to 1 MB of expanded MMU addressing. The device includes two chain-linked DMA channels, two enhanced UARTs capable of up to 512 Kbps, and two 16-bit counter/timers. It operates within a temperature range of 0°C to +70°C and utilizes a 49-pin QFN package.

Feature Summary

• Code compatible with ZiLOG Z80 CPU while offering extended instructions and faster execution speeds.
• Incorporates two chain-linked DMA channels for nonstop operation between peripherals.
• Features three low power-down modes including Stop Mode and Standby Mode to reduce consumption.
• Includes an on-chip oscillator/generator and a clock-doubler feature allowing internal speed to exceed external input.

Applications

• Systems requiring backward compatibility with existing Z80 devices but needing higher performance.
• Applications utilizing asynchronous serial communication interfaces (ASCI) with FIFO buffers.
• Embedded designs requiring direct memory access without stopping the CPU continuously.
• Power-sensitive systems utilizing specific low-power stop or standby modes.

Procurement Notes

Verify the specific suffix 'VEC00TR' against official documentation to confirm the 49-pin QFN package and tape-and-reel orientation. Confirm that the 33 MHz speed grade matches system timing requirements. Check for any environmental compliance declarations associated with this specific ordering code.

Selection Notes

Select this component when Z80 instruction set compatibility is mandatory alongside extended I/O resources like dual ASCIs and DMA. Consider the 33 MHz speed grade if system latency requires high-frequency processing. Evaluate the 49-pin QFN package constraints against PCB layout capabilities compared to PLCC or DIP alternatives.

Part Context

This part belongs to the Z8S180 series, which enhances the original Z80180 design. It integrates system resources such as MMU, timers, and serial ports directly onto the die. The series supports various packaging styles including PLCC, DIP, and QFP, with this specific variant utilizing a compact QFN form factor.
