2 / 91 page 2S29CD016G S29CD016_00_A4 November 5, 2004 Ad va n c e In f o rm a t i o n General Description The S29CD016G is a 16 Megabit, 2.5 Volt-only single power supply burst mode flash memory device. The device can be configured for 524,288 double words. The device can also be programmed in standard EPROM programmers. To eliminate bus contention, each device includes separate chip enable (CE#), write enable (WE#), and output enable (OE#) controls. Additional control inputs are required for synchronous burst operations: Load Burst Address Valid (ADV#), and Clock (CLK). Each device requires only a single 2.5 or 2.6 Volt power supply (2.5 V to 2.75 V) for both read and write functions. A 12.0-volt VPP is not required for program or erase operations, although an acceleration pin is available if faster program- ming performance is required. The device is entirely command set compatible with the JEDEC single-power- supply Flash standard. The software command set is compatible with the com- mand sets of the 5 V Am29F and 3 V Am29LV Flash families. Commands are written to the command register using standard microprocessor write timing. Register contents serve as inputs to an internal state-machine that controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. The Unlock Bypass mode facilitates faster programming times by requiring only two write cycles to program data instead of four. The Simultaneous Read/Write architecture provides simultaneous operation by dividing the memory space into two banks. The device can begin programming or erasing in one bank, and then simultaneously read from the other bank, with zero latency. This releases the system from waiting for the completion of program or erase operations. See “Simultaneous Read/Write Operations Overview and Re- strictions” on page 14. The device provides a 256-byte SecSi™ (Secured Silicon) Sector with an one- time-programmable (OTP) mechanism. In addition, the device features several levels of sector protection, which can dis- able both the program and erase operations in certain sectors or sector groups: Persistent Sector Protection is a command sector protection method that re- places the old 12 V controlled protection method; Password Sector Protection is a highly sophisticated protection method that requires a password before changes to certain sectors or sector groups are permitted; WP# Hardware Pro- tection prevents program or erase in the two outermost 8 Kbytes sectors of the larger bank. The device defaults to the Persistent Sector Protection mode. The customer must then choose if the Standard or Password Protection method is most desirable. The WP# Hardware Protection feature is always available, independent of the other protection method chosen. The VersatileI/O™ (VCCQ) feature allows the output voltage generated on the device to be determined based on the VIO level. This feature allows this device to operate in the 1.8 V I/O environment, driving and receiving signals to and from other 1.8 V devices on the same bus. The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin, by reading the DQ7 (Data# Polling), or DQ6 (toggle) |
