Signal descriptions
See Figure 1: Logic diagram and Table 1: Signal names, for a brief overview of the signals
connect-ed to this device.
2.1
Address inputs (A0-A22)
Addresses A0-A21 are common inputs for the Flash memory and PSRAM components. The
other lines (A22) is an input for the Flash memory component only.
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 signal (E_F) and through the Write Enable signal (W_F), while the PSRAM is accessed
through the Chip Enable signal (E_P) and the Write Enable signal (W_P).
2.2
Data input/output (DQ0-DQ15)
The Data I/O output the data stored at the selected address during a Bus Read operation or
input a command or the data to be programmed during a Bus Write operation.
For the PSRAM component, the upper Byte Data inputs/outputs (DQ8-DQ15) carry the data
to or from the upper part of the selected address when Upper Byte Enable (UB_P) is driven
Low. The lower Byte Data inputs/outputs (DQ0-DQ7) carry the data to or from the lower part
of the selected address when Lower Byte Enable (LB_P) is driven Low. When both UB_P and
LB_P are disabled, the Data inputs/outputs are high impedance.
2.3
Latch Enable (L)
The Latch Enable pin is common to the Flash memory and PSRAM components.
For details of how the Latch Enable signal behaves, please refer to the datasheets of the
respective memory components: M69KB096AM for the PSRAM and M58LR128HTB for the
Flash memory.
2.4
Clock (K)
The Clock input pin is common to the Flash memory and PSRAM components.
For details of how the Clock signal behaves, please refer to the datasheets of the respective
memory components: M69KB096AM for the PSRAM and M58LR128HTB for the Flash
memory.
