The 1.8 Volt-only memory device is designed to be programmed in-system with the
standard 1.8-volt Vcc supply. A 12.0 volt Vpp is not required for program or erase
operations, although an acceleration pin is available if faster write performance is
required. The device is a boot-sectored device, consisting of 255 x 32kW .
The flash device has two read modes: asynchronous read and synchronus burst mode
read. The device powers up in an asynchronous read mode. In the linear continuous burst
mode, the device delivers a continuous sequential word stream starting at the specified
word and continuing until the end of the memory or until the user loads in a new
starting address or stops the burst advance. The burst mode read operation is a
synchronous operation tied to the rising edge of the clock. The microprocessor supplies
only the initial address; all subsequent addresses are automatically generated by the
device at the rising edge of subsequent clock cycles. The burst read cycle consists of an
address phase and a corresponding data phase. The device also is capable of Burst
Suspend and Burst Resume operations.
User Interface Hardware
LCD
The color LCD is 96 lines x 64 rows. The interface includes a reset signal from the UPP, a
serial control with 3-wire, which is also from UPP (CS, Data CLK), and two power supplies
(1.8V for digital and 2.8V for analog) circuitries. The LCD also has the booster output that
needs to be connected to a booster capacitor.
The LCD is controlled by UI SW and control signals.
The booster capacitor (C309 1µF) is connected between a booster pin (Vout) and a
ground. The capacitor stores boosting voltage.
Keyboard
The keyboard design includes up, down, left, and right navigation keys; two soft keys;
and 12 number keys. The power key is located on top.
Power Key
All signals for the keyboard come from the UPP ASIC, except the power key signal, which
is connected directly to the UEM. Pressing the power key creates an interrupt and
connects the PWONX to the GND.
