13.1.2 Features
128 KByte Flash Module (S12FTMRC128K1V1)
13.1.2.1 P-Flash Features
• 128 Kbytes of P-Flash memory composed of one 128 Kbyte Flash block divided into 256 sectors
of 512 bytes
• Single bit fault correction and double bit fault detection within a 32-bit double word during read
operations
• Automated program and erase algorithm with verify and generation of ECC parity bits
• Fast sector erase and phrase program operation
• Ability to read the P-Flash memory while programming a word in the D-Flash memory
• Flexible protection scheme to prevent accidental program or erase of P-Flash memory
13.1.2.2 D-Flash Features
• 4 Kbytes of D-Flash memory composed of one 4 Kbyte Flash block divided into 16 sectors of 256
bytes
• Single bit fault correction and double bit fault detection within a word during read operations
• Automated program and erase algorithm with verify and generation of ECC parity bits
• Fast sector erase and word program operation
• Protection scheme to prevent accidental program or erase of D-Flash memory
• Ability to program up to four words in a burst sequence
13.1.2.3 Other Flash Module Features
• No external high-voltage power supply required for Flash memory program and erase operations
• Interrupt generation on Flash command completion and Flash error detection
• Security mechanism to prevent unauthorized access to the Flash memory
