... GENERAL DESCRIPTION The DS1217M is a nonvolatile RAM designed for portable applications requiring a rugged and durable package. The nonvolatile cartridge has memory capacities from 64k 512k x 8. The cartridge is accessed in continuous 32k byte banks. Bank switching is accomplished under software control by pattern recognition from the address bus. A card edge connector is required for connection to a host system ...

... CC Write Mode The DS1217M is in the write mode whenever both the WE and CE signals are in the active (low) state after address inputs are stable. The last occurring falling edge of either will determine the start of the write cycle. The write cycle is terminated by the first rising edge of either CE or WE. All address inputs must be kept valid throughout the write cycle ...

... A8 through A11) must be executed to guarantee that pattern entry starts with the first set of 3 bits. Each set of address inputs is entered into the DS1217M by executing read cycles. The first 11 cycles must match the exact bit pattern as shown in Table 2. The last five cycles must match the exact bit pattern for addresses A9, A10, and A11 ...
