Flash Memory
Architecture
AT89C5131 features two on-chip Flash memories:
Flash memory FM0:
containing 16/32 Kbytes of program memory (user space) organized into 128-byte
pages,
Flash memory FM1:
3 Kbytes for bootloader and Application Programming Interfaces (API).
The FM0 supports both parallel programming and Serial In-System Programming (ISP)
whereas FM1 supports only parallel programming by programmers. The ISP mode is
detailed in the “In-System Programming” section.
All Read/Write access operations on Flash memory by user application are managed by
a set of API described in the “In-System Programming” section.
Figure 14. Flash Memory Architecture
FM0 Memory Architecture
The Flash memory is made up of 4 blocks (see Figure 14):
1.
The memory array (user space) 16/32 Kbytes
2.
The Extra Row
3.
The Hardware security bits
4.
The column latch registers
User Space
This space is composed of a 16/32 Kbytes Flash memory organized in 128/256 pages
of 128 bytes. It contains the user’s application code.
Extra Row (XRow)
This row is a part of FM0 and has a size of 128 bytes. The extra row may contain infor-
mation for bootloader usage.
Hardware Security Space
The hardware security space is a part of FM0 and has a size of 1 byte.
The 4 MSB can be read/written by software. The 4 LSB can only be read by software
and written by hardware in parallel mode.
Column Latches
The column latches, also part of FM0, have a size of full page (128 bytes).
The column latches are the entrance buffers of the three previous memory locations
(user array, XRow and Hardware security byte).
