15. 512-K/1-M bit Flash Memory
Overview
There are three methods available for writing/deleting data to/from flash memory :
1. Parallel writer
2. Serial dedicated writer
3. Program runtime write/delete
Overview of 512-K/1-M bit flash memory
512-Kbit flash memory is arrayed in bank FFH on the CPU memory map, 1-Mbit flash memory is arrayed in bank
FEH to FFH on the CPU memory map. The flash memory interface circuit provides read and program access
from the CPU.
Since instructions from the CPU are carried out via the flash memory interface circuit, flash memory can be
overwritten at the implementation level. This allows you to efficiently improve programs and data.
Features of 512-K/1-M bit Flash Memory
512-Kbit flash memory : 64 KWords
× 8-bit/32 KWords × 16-bit (16-Kbyte + 8-Kbyte + 8-Kbyte + 32-Kbyte)
sector architecture
1-Mbit flash memory
: 128 KWords
× 8-bit/64 KWords × 16-bit (16-Kbyte + 8-Kbyte + 8-Kbyte + 32-Kbyte +
64-Kbyte) sector architecture
Auto program algorithm (Embedded Algorithm : same as MBM29LV200)
On-chip delete suspend/delete resume functions
Data polling, write/delete completion detection through toggle bit
Write/delete completion detection from CPU overwrite
Sector-specific deletion available (sectors can be combined as desired)
Write/delete iterations (minimum) : 10,000
Notes : There is no function to read the manufacture or device code.
These codes also cannot be accessed through commands.
Flash memory write/delete
It is not possible to simultaneously write to and read from flash memory.
When writing to or deleting from flash memory, first copy the program residing in flash memory into RAM,
then execute the program copied into RAM. This will allow you to write to flash memory.
