DESCRIPTION  
I/O0  
I/O7  
The Microchip Technology Inc. 28C16A is a CMOS 16K  
non-volatile electrically Erasable PROM. 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.
