Description

The ICM7211 (LCD) and ICM7212 (LED) devices constitute a family of non-multiplexed four-digit seven-segment CMOS display decoder-drivers.

The ICM7211 devices are configured to drive conventional LCD displays by providing a complete RC oscillator, divider
chain, backplane driver, and 28 segment outputs.

The ICM7212 devices are configured to drive commonanode LED displays, providing 28 current-controlled, low leakage, open-drain N-Channel outputs. These devices provide a brightness input, which may be used at normal logic levels as a display enable, or with a potentiometer as a continuous display brightness control.

The ICM7211 are available with multiplexed or microprocessor input configurations. The multiplexed versions provide four data inputs and four Digit Select inputs. This configuration is suitable for interfacing with multiplexed BCD or binary output devices, such as the ICM7217, ICM7226, and ICL7135. The microprocessor versions provide 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 standard devices of the ICM7211 will provide two different decoder configurations. The basic device will decode the four bit binary inputs into a seven-segment alphanumeric hexadecimal output. The "A" versions will provide the "Code B" output code, i.e., 0-9, dash, E, H, L, P, blank. Either device will correctly decode true BCD to seven-segment decimal outputs.
