This document should be read in conjunction with the M29DW640D and M69AW048B datasheets. Recommended operating conditions do not allow more than one of the internal memory devices to be active at the same time. The memory is offered in an LFBGA73 (8 x 11.6mm, 0.8 mm pitch) package and is supplied with all the bits erased (set to ‘1’). Figure 2.

Address Inputs (A0-A21). Address lines A0-A20 are common inputs for the Flash Memory and PSRAM components. Address line A21 is an input that is common for the two Flash Memory components. The Address Inputs select the cells in the memory array to access during Bus Read operations. During Bus Write operations they control the commands sent to the Command Interface of the internal state machine. The Flash memory is accessed through the Chip Enable (EF) and Write Enable (W) signals, while the PSRAM is accessed through two Chip Enable signals (E1S and E2S) and the Write Enable signal (W). Data Inputs/Outputs (DQ0-DQ7). The Data I/O outputs the data stored at the selected address during a Bus Read operation. During Bus Write operations they represent the commands sent to the Command Interface of the Program/Erase Controller. Data Inputs/Outputs (DQ8-DQ14). The Data I/O outputs the data stored at the selected address during a Bus Read operation when BYTE is High, VIH. When BYTE is Low, VIL, these pins are not used and are high impedance. During Bus Write operations the Command Register does not use these bits. When reading the Status Register these bits should be ignored. Data Input/Output or Address Input (DQ15A– 1). When BYTE is High, VIH, this pin behaves as a Data Input/Output pin (as DQ8-DQ14). When BYTE is Low, VIL, this pin behaves as an address pin; DQ15A–1 Low will select the LSB of the addressed Word, DQ15A–1 High will select the MSB. Throughout the text consider references to the Data Input/Output to include this pin when BYTE is High and references to the Address Inputs to include this pin when BYTE is Low except when stated explicitly otherwise. Flash-1 Chip Enable (EF1) and Flash-2 Chip Enable (EF2). The Chip Enable input activates the memory to which it is attached, allowing Bus Read and Bus Write operations to be performed. When Chip Enable is High, VIH, all other pins are ignored. Output Enable (G). The Output Enable, G, controls the Bus Read operation of the Flash Memory and PSRAM components. Write Enable (W). The Write Enable, W, controls the Bus Write operation of the Flash Memory and PSRAM components. VPP/Write VPP/Write Protect (VPP/WP). The Protect pin provides two functions. The VPP function allows the Flash memory to use an external 6/19 high voltage power supply to reduce the time required for Program operations. This is achieved by bypassing the unlock cycles and/or using the multiple Word (2 or 4 at-a-time) or multiple Byte Program (2, 4 or 8 at-a-time) commands. The Write Protect function provides a hardware method of protecting the four outermost boot blocks (two at the top, and two at the bottom of the address space). When V PP/Write Protect is Low, VIL, the memory protects the four outermost boot blocks; Program and Erase operations in these blocks are ignored while VPP/Write Protect is Low, even when RPF is at VID. When VPP/Write Protect is High, VIH, the memory reverts to the previous protection status of the four outermost boot blocks (two at the top, and two at the bottom of the address space). Program and Erase operations can now modify the data in these blocks unless the blocks are protected using Block Protection. When V PP/Write Protect is raised to VPP the memory automatically enters the Unlock Bypass mode. When V PP/Write Protect returns to VIH or VIL normal operation resumes. During Unlock Bypass Program operations the memory draws IPP from the pin to supply the programming circuits. See the description of the Unlock Bypass command in the Command Interface section. The transitions from VIH to V PP and from V PP to VIH must be slower than tVHVPP. See the M29DW640D datasheet for more details. Never raise VPP/Write Protect to VPP from any mode except Read mode, otherwise the memory may be left in an indeterminate state. The VPP/Write Protect pin must not be left floating or unconnected or the device may become unreliable. A 0.1µF capacitor should be connected between the V PP/Write Protect pin and the VSS Ground pin to decouple the current surges from the power supply. The PCB track widths must be sufficient to carry the currents required during Unlock Bypass Program, I PP. Reset/Block Temporary Unprotect (RPF). The Reset/Block Temporary Unprotect pin can be used to apply a Hardware Reset to the memory or to temporarily unprotect all Blocks that have been protected. Note that if V PP/WP is at VIL, then the two outermost boot blocks will remain protected even if RPF is at VID. A Hardware Reset is achieved by holding Reset/ Block Temporary Unprotect Low, V IL, for at least tPLPX. After Reset/Block Temporary Unprotect goes High, V IH, the memory will be ready for Bus Read and Bus Write operations after tPHEL or M74DW66500B tRHEL, whichever occurs last. See the M29DW640D datasheet for more details. Holding RPF at VID will temporarily unprotect the protected Blocks in the memory. Program and Erase operations on all blocks will be possible. The transition from VIH to VID must be slower than tPHPHH. Ready/Busy Output (RB). The Ready/Busy pin is an open-drain output that can be used to identify when the Flash memory is performing a Program or Erase operation. During Program or Erase operations Ready/Busy is Low, VOL. Ready/Busy is high-impedance during Read mode, Auto Select mode and Erase Suspend mode. After a Hardware Reset, Bus Read and Bus Write operations cannot begin until Ready/Busy becomes high-impedance. The use of an open-drain output allows the Ready/ Busy pins from several memories to be connected to a single pull-up resistor. A Low will then indicate that one, or more, of the memories is busy. Byte/Word Organization Select (BYTE). The Byte/Word Organization Select pin is used to switch between the x8 and x16 Bus modes of the Flash memory. When Byte/Word Organization Select is Low, V IL, the Flash memory is in x8 mode, when it is High, V IH, the Flash memory is in x16 mode. PSRAM Chip Enable inputs (E1P, E2P). The Chip Enable inputs activate the PSRAM control logic, input buffers and decoders. E1 P at VIH with E2P at VIH deselects the memory, reducing the power consumption to the standby level, whereas E2P at VIL deselects the memory and reduces the power consumption to the Power-down level, re- gardless of the level of E1P. E1P and E2P can also be used to control writing to the PSRAM memory array, while WP remains at VIL. It is not allowed to set EF1 or EF2 at VIL, E1P at VIL and E2P at V IH at the same time. PSRAM Upper Byte Enable (UBP). The Upper Byte Enable input enables the upper byte for PSRAM (DQ8-DQ15). UBP is active low. PSRAM Lower Byte Enable (LBP). The Lower Byte Enable input enables the lower byte for PSRAM (DQ0-DQ7). LBP is active low. VCCF Supply Voltage (2.7 to 3.3V). VCCF provides the power supply for Flash memory operations (Read, Program and Erase). The Command Interface is disabled when the VCCF Supply Voltage is less than the Lockout Voltage, VLKO . This prevents Bus Write operations from accidentally damaging the data during power up, power down and power surges. If the Program/ Erase Controller is programming or erasing during this time then the operation aborts and the memory contents being altered will be invalid. A 0.1µF capacitor should be connected between the VCCF Supply Voltage pin and the VSS Ground pin to decouple the current surges from the power supply. The PCB track widths must be sufficient to carry the currents required during Program and Erase operations, ICC3. VCCP Supply Voltage (2.7 to 3.3V). VCCP provides the power supply for the PSRAM. VSS Ground. VSS is the ground reference for all voltage measurements in the Flash and PSRAM chips. 7/19 M74DW66500B FUNCTIONAL DESCRIPTION The Flash Memory and PSRAM components have a common power supply. The components are distinguished by four chip enable inputs: EF1 for one Flash memory, EF2 for the other, and E1S and E2S for the PSRAM. Recommended operating conditions do not allow more than one of the Flash Memory or PSRAM component to be in active mode at the same time. The most common example is simultaneous read operations on the Flash Memory and PSRAM components which would result in a data bus contention. Therefore it is recommended to put two of the components in the high impedance state when reading from the third (see Table 2 Main Operation Modes for details). Table 2.

X = Don’t Care (V IL or VIH). 2. UB P and LBP are tied together. 3. This table is valid when BYTE = VIH. This table is also valid when BYTE = VIL , with the only difference that DQ15-DQ8 are always high impedance when the Flash Memory components are being accessed. 4.
