Product details
Overview
DSC6001HE1A-018.4320 from Microchip Technology is an ultra-low-power, single-output MEMS oscillator with 18.432 MHz output frequency, ±50 ppm frequency stability over –20°C to +70°C, 1.6 mm × 1.2 mm VFLGA package, and active/standby current of 1.3 mA / 12 µA - designed as a drop-in replacement for quartz oscillators in space-constrained, battery-powered IoT and consumer devices.
For engineers reviewing the DSC6001HE1A-018.4320 datasheet, DSC6001HE1A-018.4320 pinout, DSC6001HE1A-018.4320 application, or DSC6001HE1A-018.4320 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed MEMS architecture, real-world timing performance (32 psRMS period jitter), and direct-fit alternatives for industrial and extended-commercial designs.
Technical Context
The DSC6001HE1A-018.4320 implements a MEMS resonator with integrated temperature sensor, digital control & compensation, PLL-based VCO, and CMOS output driver - delivering stable 18.432 MHz clocking without external load capacitors. Its architecture eliminates crystal aging and mechanical shock sensitivity while maintaining full compatibility with standard 4-pin oscillator footprints.
Pin 1 is configured as Output Enable (OE) with internal 300 kΩ pull-up resistor; Pin 3 provides rail-to-rail CMOS output; supply regulation supports 1.71–3.63 V operation; and startup time is guaranteed ≤1.3 ms from 90% VDD. The device meets AEC-Q100 stress requirements and MIL-STD-883 vibration immunity standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 18.432 MHz - precise UART/USB audio reference frequency, factory-trimmed and non-adjustable. |
| Frequency Stability | ±50 ppm - covers initial tolerance, temperature drift (–20°C to +70°C), and supply voltage variation. |
| Supply Current | 1.3 mA active / 12 µA standby at 1.8 V - enables multi-year battery life in wearables and sensors. |
| Startup Time | ≤1.3 ms - time from 90% VDD to valid clock edge, critical for fast-wake microcontroller systems. |
| Period Jitter (RMS) | 32 ps RMS at 27 MHz (typical); extrapolated <40 ps RMS at 18.432 MHz - sufficient for USB 2.0 and Bluetooth PHY timing. |
| Output Drive | Standard drive (DSC60x1): >3 mA sink/source at 20%/80% VDD - drives 10 pF load with <2 ns rise/fall times. |
| Package | 4-lead VFLGA, 1.6 mm × 1.2 mm × 0.425 mm - industry's smallest MEMS oscillator footprint, compatible with 0402 reflow profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MEMS oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DSC6001HI1A-018.4320 | Same package, drive strength, and frequency; ±25 ppm stability instead of ±50 ppm. | Required for industrial-temp (–40°C to +85°C) designs needing tighter frequency tolerance. | Select when design mandates <±25 ppm drift over full industrial range - adds ~$0.08/unit cost. |
| SiT1533AI-H4-33E-18.432000 | 1.5×1.2 mm LGA, 1.8 V only, ±50 ppm, 1.5 mA active current - slightly larger footprint, narrower VDD range. | Suitable where SiTime's broader automotive qualification (AEC-Q200 Grade 2) is prioritized over Microchip's AEC-Q100. | Choose if existing layout accommodates 1.5×1.2 mm pad stack and 1.8 V rail is dedicated; verify 1.5 mA vs. 1.3 mA impact on battery runtime. |
Compared with DSC6001HE1A-018.4320, the DSC6001HI1A-018.4320 offers superior temperature stability at industrial grade, while the SiT1533AI-H4-33E-18.432000 provides alternate MEMS vendor qualification - both require no PCB changes but differ in supply range, thermal spec, and cost-per-unit trade-offs.

FAQ
What is the operating temperature range for DSC6001HE1A-018.4320?
DSC6001HE1A-018.4320 is rated for extended commercial temperature range: –20°C to +70°C. This specification is explicitly defined in the product identification system ('E' suffix) and confirmed in Table 1-1 of DS20005625C. Operation outside this range may result in frequency deviation exceeding ±50 ppm or increased startup time.
Does DSC6001HE1A-018.4320 require external load capacitors?
No, DSC6001HE1A-018.4320 does not require external load capacitors. As a fully integrated MEMS oscillator, all timing elements - including resonator, compensation circuitry, and output driver - are contained within the 1.6 mm × 1.2 mm VFLGA package. Only a 0.1 µF ceramic bypass capacitor on VDD (Pin 4) is required per datasheet layout guidelines.
Is DSC6001HE1A-018.4320 pin-compatible with quartz crystal oscillators?
Yes, DSC6001HE1A-018.4320 uses a standard 4-pin CMOS oscillator footprint and is explicitly documented as a "drop-in replacement" for quartz devices in 1.6 mm × 1.2 mm VFLGA. Pin mapping (OE/GND/OUT/VDD) matches industry-standard oscillator pinouts, enabling direct substitution without PCB modification.
What is the function of Pin 1 on DSC6001HE1A-018.4320?
Pin 1 on DSC6001HE1A-018.4320 is configured as Output Enable (OE) with an internal 300 kΩ pull-up resistor. When held high (or left floating), the device outputs the 18.432 MHz clock on Pin 3; when driven low, the output enters high-impedance state and supply current drops to 12 µA standby level.
Can DSC6001HE1A-018.4320 be used in automotive under-hood applications?
DSC6001HE1A-018.4320 meets AEC-Q100 stress test requirements and exhibits excellent shock/vibration immunity per MIL-STD-883, but its extended commercial temperature range (–20°C to +70°C) limits use to cabin-located modules like infotainment or rear-view cameras. For under-hood placement, the industrial-grade DSC6001HI1A-018.4320 (–40°C to +85°C) is required.
