WZMicro - Affordable Quality Electronics

Combine The Z-80 SBC and SB8466 interface card, you will have a full embedded controlled system, you can use it in any project you can think of, it is only limit to your imagination! .

The SB8010 is a highly versatile SBC comprised of a Z-80 microprocessor, 4 general purpose 28 pin sockets for byte-wide ROM and/or RAM chips, a Z-80 CTC counter-timer, and a serial I/O port (UART) using Intel's 8251. A bootstrap option is provided for loading an operating system into main memory using an on-board PROM.

On-board memory can be mapped in various ways to match the memory chips selected. The mapping options are accomplished using a PROM. The user may install his won PROM if a different mapping is desired. However, the six mappings provided should satisfy most users.

The serial I/O chip uses the counter-timer chip as the clock source for both receiver and transmitter to that baud rate is programmable by software. RS232 buffers are provided for all the serial outputs and inputs. In an interrupt driven system, the serial chip (8251) uses the CTC as an interrupt controller, enabling the serial chip (8085 peripheral) to benefit from the sophisticated Z-80 interrupt scheme.

The CTC can also be used as an interrupt controller for external events as well as a general purpose counter and / or timer.
