4-Digit, LCD Display Driver
The ICM7211AM device is a non-multiplexed four-digit
seven-segment CMOS LCD display decoder-driver.
This device is configured to drive conventional LCD displays
by providing a complete RC oscillator, divider chain,
backplane driver, and 28 segment outputs.
It also has a microprocessor compatible input configuration,
which provides data input latches and Digit Address latches
under control of high-speed Chip Select inputs. These devices
simplify the task of implementing a cost-effective
alphanumeric seven-segment display for microprocessor
systems, without requiring extensive ROM or CPU time for
decoding and display updating.
The ICM7211AM provides the “Code B” output code, i.e.,
0-9, dash, E, H, L, P, blank, but will correctly decode true
BCD to seven-segment decimal outputs.
Features
• Four Digit Non-Multiplexed 7 Segment LCD Display
Outputs with Backplane Driver
• Complete Onboard RC Oscillator to Generate Backplane
Frequency
• Backplane Input/Output Allows Simple Synchronization of
Slave-Devices to a Master
• Provides Data and Digit Address Latches Controlled by
Chip Select Inputs to Provide a Direct High Speed
Processor Interface
• Decodes Binary to Code B (0-9, Dash, E, H, L, P, Blank)
