FAQ

What is the maximum sink current capability of the IRTX pin on the MAXQ617V-L000+T?

The MAXQ617V-L000+T IRTX pin provides a minimum sink current of 200mA at 1.8V supply, enabling direct drive of standard IR LEDs without external transistors. This specification is guaranteed across the full operating temperature range (–20°C to +70°C) and is measured with VIRTX ≥ 0.25V. The pin's output structure supports robust pulsed operation required for IR carrier modulation.

Does the MAXQ617V-L000+T require an external crystal or resonator?

No, the MAXQ617V-L000+T includes a fully integrated 12MHz oscillator with ±1% accuracy over –20°C to +70°C, eliminating the need for external timing components. This internal oscillator powers the system clock and supports single-cycle instruction execution at up to 12 MIPS. External crystals are neither required nor supported for primary clocking.

How does the power-fail detection feature work on the MAXQ617V-L000+T?

The MAXQ617V-L000+T features a dedicated power-fail comparator with user-configurable threshold (1.64–1.70V default). When VDD drops below the selected VPFW level, it asserts a power-fail warning flag and can generate an interrupt. If voltage continues falling to VRST (1.61–1.67V), a hardware reset is triggered. This dual-threshold design allows firmware to initiate graceful shutdown before reset occurs.

What package type and ball count does the MAXQ617V-L000+T use?

The MAXQ617V-L000+T is packaged in a 20-ball Wafer-Level Package (WLP) with 0.4mm pitch and JEDEC MO-220 compliant footprint. Key balls include VDD (B4), GND (C2), REG18 (C4), RESET (A4), IRTX (C1), IRRX (B1), and ten GPIO balls (P0.0–P0.5, P1.4–P1.7). The package is optimized for space-constrained remote control PCBs.

Can the MAXQ617V-L000+T perform IR learning without external amplification?

Yes, the MAXQ617V-L000+T integrates a dedicated IR receive amplifier on the IRRX pin with programmable gain and 50ns pulse-width rejection filtering. This allows direct connection of standard IR photodiodes without external op-amps or bias networks. The amplifier supports learning of common protocols including NEC, RC-5, and Sony, with hardware-assisted carrier burst counting.
