The 28C16A is accessed like a static RAM for the read or write cycles without the need of external components. Dur- ing a “byte write”, the address and data are latched internally, freeing the microprocessor address and data bus for other operations. Following the initiation of write cycle, the device will go to a busy state and auto- matically clear and write the latched data using an internal control timer. To determine when a write cycle is complete, the 28C16A uses Data polling. Data poll- ing allows the user to read the location last written to when the write operation is complete. CMOS design and processing enables this part to be used in systems where reduced power consumption and reliability are required. A complete family of packages is offered to provide the utmost flexibility in applications.
