rd000603-0814 page 1 of 10 overview zilog?s mini-z zneo 28-pin module is a 28-p in dual inline pin module designed for the engineer, student and enthusiast to quickly develop prototypes, proofs of concept and demonstrations as well as to provide the functionality requ ired for hands-on learning. the mini-z zneo 28-pin module is a single-board computer that is easy to use, and it boasts a wide support base of free application resources. the module, which features the 16-bit zneo cpu-based z16f2810 mcu, is designed to be pin-compatible with the parallax bs2 series of stamp modules and with basic micro?s basic atom pro 28-m module. this compatibility in the module?s design allows you to utilize differing vendors? base boards which you may already possess in your development arsenal. the mini-z zneo 28-pin modu le ships preprogrammed with a boot loader and a control shell that can be accessed via the serial port. th is serial port access allows developers to control the module from a terminal emulatio n program (such as hyperterminal) and to upload user applicatio n code as a hex file. the module is fully compatible with zilog? s zds ii ide version 4. 12.0 for zneo-based mcus. you can write your programs in c and assembly, then compile and upload your hex file via the serial port to the module. you can also attach a usb smart cable (not included) and have full control over the zneo cpu, including interactive debugging sessions. figure 1. the zneo-based mini-z zneo 28-pin module notch mini debug adapter pin 1 reference design mini-z ? zneo 28-pin module rd000603-0814
