GENERAL DESCRIPTION  
The Pm39F010/020/040 are 1 Mbit/2 Mbit/4 Mbit 5.0 Volt-only Flash Memories. These devices are designed to use  
a single low voltage, range from 4.5 Volt to 5.5 Volt, power supply to perform read, erase and program operations.  
The 12.0 Volt VPP power supply for program and erase operations are not required. The devices can be programmed  
in standard EPROM programmers as well.  
The memory arrays of Pm39F010/020/040 are divided into uniform 4 Kbyte sectors or uniform 64 Kbyte blocks  
(sector group - consists of sixteen adjacent sectors). The sector or block erase feature allows users to flexibly  
erase an memory area as small as 4 Kbyte or as large as 64 Kbyte by one single erase operation without affecting  
the data in others. The chip erase feature allows the whole memory array to be erased in one single erase opera-  
tion. The devices can be programmed on a byte-by-byte basis after performing the erase operation.  
The devices have a standard microprocessor interface as well as a JEDEC standard pin-out/command set. The  
program operation is executed by issuing the program command code into command register. The internal control  
logic automatically handles the programming voltage ramp-up and timing. The erase operation is executed by  
issuing the chip erase, block, or sector erase command code into command register. The internal control logic  
automatically handles the erase voltage ramp-up and timing. The preprogramming on the array which has not been  
programmed is not required before an erase operation. The devices offer Data# Polling and Toggle Bit functions, the  
progress or completion of program and erase operations can be detected by reading the Data# Polling on I/O7 or  
the Toggle Bit on I/O6.  
The Pm39F010/020/040 are manufactured on PMC’s advanced nonvolatile CMOS technology, P-FLASH™. The  
devices are offered in 32-pin PDIP, PLCC and VSOP packages with access time of 55 and 70 ns.
