NXP Semiconductors PCF2105
The PCF2105 is optimized for chip-on-glass applications. The PCF2105 is a low power CMOS LCD controller/driver, designed to drive a split screen dot matrix LCD of 1 or 2 lines by 24 characters or 2 or 4 lines by 12 characters with a 5 × 8 dot format. The PCF2105 interfaces to most microcontrollers via a 4 or 8-bit parallel bus, or via the 2-wire I2C-bus.| Part No. | PCF2105 |
