PCA8546 4 x 44 automotive LCD driver Rev. 1 — 13 November 2013 Product data sheet 1. General description The PCA8546 is a peripheral device which generates the drive signals for any multiplexed LCD containing up to four backplanes, and up to 176 elements. The PCA8546 is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus (PCA8546A) or a three line unidirectional SPI-bus (PCA8546B). Communication overheads are minimized using a display RAM with auto-incremented addressing. For a selection of NXP LCD segment drivers, see Table 38 on page 53. 2. Features and benefits            AEC-Q100 grade 3 compliant for automotive applications Single-chip 176 elements LCD controller and driver Wide range for digital power supply: from 1.8 V to 5.5 V LCD supply range from 2.5 V up to 9 V LCD and logic supplies may be separated Low power consumption Four backplanes and selectable display bias configuration On-chip RAM for display data storage 400 kHz I2C-bus interface (PCA8546A) 5 MHz SPI-bus interface (PCA8546B) Programmable frame frequency in the range of 60 Hz to 300 Hz in steps of about 10 Hz; factory calibrated  176 segments driven allowing:  up to 22 7-segment alphanumeric characters  up to 11 14-segment alphanumeric characters  any graphics of up to 176 elements  Manufactured in silicon gate CMOS process  Extended operating temperature range up to 95 C 3.

PCA8546 Product data sheet Suitability for use in automotive applications — This NXP Semiconductors product has been qualified for use in automotive applications. Unless otherwise agreed in writing, the product is not designed, authorized or warranted to be suitable for use in life support, life-critical or safety-critical systems or equipment, nor in applications where failure or malfunction of an NXP Semiconductors product can reasonably be expected to result in personal injury, death or severe property or environmental damage. NXP Semiconductors and its suppliers accept no liability for inclusion and/or use of NXP Semiconductors products in such equipment or applications and therefore such inclusion and/or use is at the customer's own risk. Applications — Applications that are described herein for any of these products are for illustrative purposes only. NXP Semiconductors makes no representation or warranty that such applications will be suitable for the specified use without further testing or modification. Customers are responsible for the design and operation of their applications and products using NXP Semiconductors products, and NXP Semiconductors accepts no liability for any assistance with applications or customer product design. It is customer’s sole responsibility to determine whether the NXP Semiconductors product is suitable and fit for the customer’s applications and products planned, as well as for the planned application and use of customer’s third party customer(s). Customers should provide appropriate design and operating safeguards to minimize the risks associated with their applications and products. NXP Semiconductors does not accept any liability related to any default, damage, costs or problem which is based on any weakness or default in the customer’s applications or products, or the application or use by customer’s third party customer(s). Customer is responsible for doing all necessary testing for the customer’s applications and products using NXP Semiconductors products in order to avoid a default of the applications and the products or of the application or use by customer’s third party customer(s). NXP does not accept any liability in this respect. Limiting values — Stress above one or more limiting values (as defined in the Absolute Maximum Ratings System of IEC 60134) will cause permanent damage to the device. Limiting values are stress ratings only and (proper) operation of the device at these or any other conditions above those given in the Recommended operating conditions section (if present) or the Characteristics sections of this document is not warranted. Constant or repeated exposure to limiting values will permanently and irreversibly affect the quality and reliability of the device. Terms and conditions of commercial sale — NXP Semiconductors products are sold subject to the general terms and conditions of commercial sale, as published at http://www.nxp.com/profile/terms, unless otherwise agreed in a valid written individual agreement. In case an individual agreement is concluded only the terms and conditions of the respective agreement shall apply.
