Product details
Overview
PCA2117DUGR/DAZ from NXP Semiconductors is an AEC-Q200 Grade 2 qualified automotive LCD controller and driver IC designed to drive 2×20 or 1×40 character dot-matrix displays with 5×8 font, support up to 200 icons, and integrate on-chip voltage multiplication (2×–4×), temperature-sensing, and programmable temperature compensation for stable VLCD across −40 °C to +105 °C. It operates from 2.5 V to 5.5 V supply rails and delivers <2 μA power-down current.
For engineers reviewing the PCA2117DUGR/DAZ datasheet, PCA2117DUGR/DAZ pinout, PCA2117DUGR/DAZ application, or PCA2117DUGR/DAZ equivalent, this page provides verified technical context, validated pin functions, confirmed automotive display use cases, and two documented alternative part numbers with explicit functional and application-level differences.
Technical Context
The PCA2117DUGR/DAZ implements a dual-bus interface-selectable I²C (two-wire) or SPI (four-wire)-with dedicated SA0 and IFS pins determining slave address and bus mode. Its internal oscillator requires no external components, though an external clock may be applied via CLK pin when OSC is tied to VDD1.
It integrates a 244-bump bare-die package with dedicated row/column driver outputs (R0–R16, C0–C99), VLCD regulation circuitry (VLCDIN/VLCDSENSE/VLCDOUT), and diagnostic features including CRC-8/XOR checksums on both buses and real-time temperature readout accessible via Read_status_reg command.

Applications
| Instrument Cluster Display | Climate Control Panel |
|---|---|
Use Scenario: Real-time rendering of speed, RPM, fuel level, warning indicators, and gear position in automotive dashboards. IC Role / Device Role / Timing Role: Primary LCD controller driving 2×20 character display with 128+ icons; manages multiplexed row/column timing and temperature-stable VLCD generation. Use Value: AEC-Q200 qualification and −40 °C to +105 °C operation ensure reliability across vehicle thermal cycles without contrast drift. |
Use Scenario: User interface for HVAC settings, temperature setpoints, fan speed, and mode selection in cabin climate systems. IC Role / Device Role / Timing Role: Character + icon driver handling dynamic text updates and persistent status icons (e.g., snowflake, sun, fan); uses icon blink for active mode feedback. Use Value: Direct icon mode reduces average current to <25 μA during standby - critical for always-on infotainment subsystems. |
| Car Radio UI | Medical Equipment Display |
Use Scenario: Displaying station name, track title, artist, time, and playback controls on OEM head units. IC Role / Device Role / Timing Role: SPI/I²C-configurable controller interfacing with host MCU; handles DDRAM updates, cursor positioning, and CGRAM symbol loading. Use Value: Programmable frame frequency (45–360 Hz) eliminates visible flicker under varying ambient lighting and camera capture conditions. |
Use Scenario: Patient monitor showing vital signs (SpO₂, pulse rate, NIBP), alarm status, and menu navigation in clinical environments. IC Role / Device Role / Timing Role: Low-power LCD driver supporting long battery life; leverages power-down mode (<2 μA) between screen updates. Use Value: On-chip voltage multiplier eliminates need for external charge pump ICs - reduces BOM count and PCB area in space-constrained medical modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD controller and driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCF8576DT/1 | Single-supply (2.5–6 V), no integrated temperature sensor, fixed 100 Hz frame rate, no icon blink hardware | Lacks AEC-Q200 qualification and temperature compensation - suitable for industrial but not automotive instrument clusters | Choose PCF8576DT/1 only if cost sensitivity outweighs need for automotive-grade stability and icon efficiency. |
| ST7066U | Parallel interface only (no I²C/SPI), no on-chip charge pump (requires external VLCD), no temperature sensing, wider VDD range (2.7–5.5 V) | Requires additional level-shifting and bias generation circuitry; higher system-level power and layout complexity | Prefer ST7066U only when legacy parallel MCU interfaces exist and external VLCD regulation is already implemented. |
Compared with PCF8576DT/1 and ST7066U, PCA2117DUGR/DAZ uniquely combines AEC-Q200 compliance, integrated temperature-compensated VLCD generation, hardware icon blink, and dual-bus flexibility - enabling lower system cost, smaller footprint, and guaranteed performance across automotive thermal extremes.

FAQ
What is the package type of PCA2117DUGR/DAZ?
PCA2117DUGR/DAZ is supplied as a bare die with 244 gold bumps, intended for flip-chip assembly onto custom substrates. It does not use a molded plastic or ceramic package - mechanical details including bump pitch and die dimensions are specified in NXP's PCA2117DUGx mechanical drawings (Figure 61, Rev. 4 datasheet).
Does PCA2117DUGR/DAZ support both I²C and SPI interfaces simultaneously?
No - PCA2117DUGR/DAZ supports either I²C or SPI, selected at power-up via the IFS pin. When IFS is pulled low, the device configures for I²C mode using SA0 to set the LSB of the 7-bit slave address; when IFS is high, it enters SPI mode with CE, SCL, SDI, and SDO active. Both interfaces cannot operate concurrently.
How does the temperature compensation feature work in PCA2117DUGR/DAZ?
PCA2117DUGR/DAZ integrates an on-die temperature sensor and allows programming four independent temperature compensation slopes (TSA–TSD) via TC_slope commands. These slopes adjust the VLCD output dynamically based on measured die temperature, maintaining consistent LCD contrast across −40 °C to +105 °C without external thermistors or calibration firmware.
What is the maximum number of user-defined characters supported by PCA2117DUGR/DAZ?
PCA2117DUGR/DAZ supports up to 48 user-defined characters stored in CGRAM, organized across three selectable RAM columns (16 characters each). Each character uses 5×8 dot format, and CGRAM access is controlled via RAM_ROM_config and Sel_mem_bank commands per the datasheet register map.
Is PCA2117DUGR/DAZ pin-compatible with earlier PCA2112 or PCA2115 variants?
No - PCA2117DUGR/DAZ is not pin-compatible with PCA2112 or PCA2115. It features a 244-bump layout optimized for higher-resolution icon support and revised VLCD regulation architecture. Migration requires PCB redesign and firmware adaptation due to differences in register mapping, command structure, and pin functionality (e.g., dedicated VLCDSENSE input).
