Product details
Overview
UCB1400BE,128 from NXP Semiconductors (formerly Philips Semiconductors) is a single-chip stereo audio codec with integrated 4-wire resistive touch screen controller and power management monitor. It implements AC '97 Rev. 2.1 interface, supports 20-bit stereo ADC/DAC, features 10-bit ADC for touch and voltage monitoring, and operates from 3.3 V supply - deployed in handheld PDAs and smart mobile phones for simultaneous audio playback, recording, touchscreen input, and battery voltage supervision.
For engineers reviewing the UCB1400BE,128 datasheet, UCB1400BE,128 pinout, UCB1400BE,128 application, or UCB1400BE,128 equivalent, key selection considerations include AC '97 Rev. 2.1 host compatibility, 20-bit audio resolution, 4-wire resistive touch support with position/pressure measurement, 10-bit ADC for external high-voltage (7.5 V) monitoring, and LQFP48 package integration for space-constrained portable designs.
Technical Context
The UCB1400BE,128 functions exclusively as an AC '97 primary codec, deriving its 12.288 MHz BIT_CLK from an internal PLL driven by a 24.576 MHz crystal connected to XTL_IN/XTL_OUT. It uses synchronous AC-link communication with fixed 48 kHz frame rate, where SYNC defines frame boundaries and SDATA_IN/SDATA_OUT carry time-division multiplexed control, PCM playback, and PCM record streams.
Its analog subsystem includes dual 20-bit sigma-delta ADCs for line/mic inputs and dual 20-bit DACs for line/headphone outputs, plus a dedicated 10-bit successive-approximation ADC with track-and-hold and analog multiplexer for touch plate sensing and four-channel 7.5 V power rail monitoring. Ten GPIO pins support programmable I/O, and interrupt generation is handled via IRQOUT and optional GPIO_INT signaling.

FAQ
What is the primary interface protocol supported by the UCB1400BE,128?
The UCB1400BE,128 implements the AC '97 Revision 2.1 interface as a primary codec only. It communicates with host controllers like the Intel XScale processor using BIT_CLK, SYNC, SDATA_IN, SDATA_OUT, and RESET signals. The device does not support secondary codec mode or non-AC '97 interfaces such as I²S or SPI. All register access and audio data transfer occur over this standardized 5-pin serial link.
Does the UCB1400BE,128 support direct headphone driving?
Yes, the UCB1400BE,128 includes integrated headphone drivers on LINE_OUT_L and LINE_OUT_R pins. These drivers feature short-circuit protection and a virtual ground circuit that enables DC-coupled output - eliminating the need for external coupling capacitors. The drivers deliver sufficient current for standard 16–32 Ω headphones while maintaining low THD+N (<0.02%) at rated output levels.
Can the UCB1400BE,128 monitor voltages above 3.3 V?
Yes, the UCB1400BE,128's 10-bit ADC supports monitoring of up to four external analog inputs with voltage ratings up to 7.5 V. This is achieved through internal scaling and clamping circuitry on the AD[3:0] pins, allowing direct connection to battery packs, LDO outputs, or other high-voltage rails without external resistor dividers - a key feature for power management in portable systems.
What touch screen technology is compatible with the UCB1400BE,128?
The UCB1400BE,128 is designed exclusively for 4-wire resistive touch screens. Its TSPX, TSMX, TSPY, and TSMY pins provide dedicated drive and sense paths for X-plate and Y-plate excitation and measurement. It does not support capacitive, surface acoustic wave (SAW), or 5-wire resistive touch technologies. Touch position, pressure, and plate resistance are all computed internally using the integrated ADC and sequencer.
Is the UCB1400BE,128 pin-compatible with other members of the UCB1400 family?
Yes, all UCB1400 variants - including UCB1400BE,128 - share identical LQFP48 pinout and electrical characteristics per the SOT313-2 package definition. Differences between variants (e.g., UCB1400BE vs. UCB1400CE) relate only to mask ROM content, factory programming, or minor test configurations - not pin function, timing, or DC parameters. System-level hardware design remains unchanged across the family.
