Chapter 2 128 Kbyte ECC Flash Module (S12FTS128K1ECCV1)
2.1.2 Features
• 128 Kbytes of Flash memory comprised of one 128 Kbyte block divided into 128 sectors of 1024
bytes with every word (two bytes) accompanied by 6 ECC parity bits
• Single bit fault correction per word during read operations
• Automated program and erase algorithm with generation of ECC parity bits
• Interrupts on Flash command completion, command buffer empty and double bit fault detection
• Fast sector erase and word program operation
• 2-stage command pipeline for faster multi-word program times
• Sector erase abort feature for critical interrupt response
• Flexible protection scheme to prevent accidental program or erase
• Single power supply for all Flash operations including program and erase
• Security feature to prevent unauthorized access to the Flash memory
• Code integrity check using built-in data compression
2.1.3 Modes of Operation
Program, erase, erase verify, and data compress operations (please refer to Section 2.4.1 for details).
2.1.4 Block Diagram
A block diagram of the Flash module is shown in Figure 2-1.
