77 / 159 page  TMS570LS3137 www.ti.com SPNS162. – SEPTEMBER 2011 4.10 Flash Memory 4.10.1 Flash Memory Configuration Flash Bank: A separate block of logic consisting of 1 to 16 sectors. Each flash bank normally has a customer-OTP and a TI-OTP area. These flash sectors share input/output buffers, data paths, sense amplifiers, and control logic. Flash Sector: A contiguous region of flash memory which must be erased simultaneously due to physical construction constraints. Flash Pump: A charge pump which generates all the voltages required for reading, programming, or erasing the flash banks. Flash Module: Interface circuitry required between the host CPU and the flash banks and pump module. Table 4-23.
