Nexperia USA Inc. 74AUP1Z04GM,132

Overview

74AUP1Z04GM,132 from Nexperia is a low-power crystal oscillator driver IC with integrated enable input, internal pull-up resistor (RPU), and bias resistor (Rbias). It functions as a Schmitt-trigger inverter-based X-tal driver for Pierce oscillator configurations, operating across 0.8 V to 3.6 V supply, supporting -40 °C to +125 °C ambient, and delivering propagation delays as low as 0.7 ns (X1→X2, VCC = 3.0–3.6 V, CL = 5 pF) in crystal timing circuits for ultra-low-power microcontrollers.

For engineers reviewing the 74AUP1Z04GM,132 datasheet, 74AUP1Z04GM,132 pinout, 74AUP1Z04GM,132 application, or 74AUP1Z04GM,132 equivalent, key selection criteria include its dual-output (X2/Y) drive capability, EN-active-LOW control with Schmitt-trigger tolerance, IOFF power-down mode at output Y, sub-75 μA ICC supply current, and compatibility with miniature XSON6 (SOT886) packaging for space-constrained timing subsystems.

Technical Context

The 74AUP1Z04GM implements a CMOS inverter core with internal Rbias (~1.07–3.11 MΩ) to bias the X1 input near mid-supply, enabling stable linear-region operation for crystal oscillation. Its EN input controls functional enable/disable: when EN = HIGH, X1 is pulled HIGH via internal RPU, X2 driven LOW, and Y driven HIGH - placing the device in low-power disable mode.

Dynamic behavior is defined by two distinct signal paths: X1→X2 (inverter path, tpd ≤ 1.7 ns @ VCC = 3.6 V, CL = 5 pF) and X1→Y (buffered path with added delay, tpd ≤ 3.8 ns under same conditions). Both outputs support load capacitances up to 30 pF and exhibit low noise overshoot/undershoot (<10% of VCC).

FAQ

What is the function of the internal Rbias resistor?

The internal Rbias resistor (1.07–3.11 MΩ) establishes a DC bias point at the X1 input near VCC/2, ensuring the inverter operates in its high-gain linear region. This is essential for reliable crystal oscillation startup and sustained amplitude in Pierce configurations, eliminating the need for an external bias network.

Can the Y output be used as the primary clock signal instead of X2?

Yes - Y is a buffered output derived from X1, offering isolation from crystal loading effects. However, it introduces additional propagation delay (e.g., 3.8 ns vs 1.7 ns for X1→X2 at VCC = 3.6 V). Use Y when signal integrity or fan-out requirements outweigh minimal timing skew constraints.

How does the EN pin behave when left unconnected?

The EN pin has no internal pull-up or pull-down; leaving it floating risks undefined operation and potential oscillation instability. It must be actively driven HIGH (to disable) or LOW (to enable) - typically tied to a GPIO or power-good signal in production designs.

Is the 74AUP1Z04GM,132 compatible with 32.768 kHz tuning-fork crystals?

Yes - the device is explicitly characterized for low-frequency crystal operation. Its low input capacitance (1.5 pF), stable Rbias, and wide VCC range make it ideal for 32.768 kHz RTC crystals, especially when paired with load capacitors C1/C2 calculated per the manufacturer's specified CL and board stray capacitance.
