FN3158.5
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 鈥淐ode B鈥?output code, i.e.,
0-9, dash, E, H, L, P, blank, but will correctly decode true
BCD to seven-segment decimal outputs.
