SP708TEN-L from MaxLinear, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | MR | input | Active-LOW manual-reset input. Triggers a reset pulse when pulled below 0.8V; has an internal ~250µA pull-up (SP708 family). TTL/CMOS compatible; can be tied to a pushbutton to ground or driven from a logic line. |
| 2 | VCC | power_in | Positive supply input. Operating range 3.0V to 5.5V for the SP708T. Bypass with a 100nF capacitor close to the pin for transient immunity. |
| 3 | GND | power_in | Ground reference for all signals. |
| 4 | PFI | input | Power-Fail comparator Input. Non-inverting input of a comparator whose inverting input is internally tied to a 1.25V reference. When VPFI drops below 1.25V, PFO goes LOW. Tie to GND or VCC when unused. |
| 5 | PFO | output | Active-LOW Power-Fail Output. HIGH when PFI > 1.25V, LOW when PFI < 1.25V. Used to interrupt the µP for an orderly power-down. |
| 6 | NC | unconnected | No connect. Leave floating or tie to any convenient net. On the SP706R/S/T this pin position is WDI; the SP708T omits the watchdog feature. |
| 7 | RESET | output | Active-LOW reset output. Pulses LOW for 200ms (typ) after VCC rises above the 3.08V reset threshold or after MR is released. Held LOW while VCC is below the reset threshold, guaranteed valid down to VCC = 1V. |
| 8 | RESET | output | Active-HIGH reset output. Complement of the active-LOW RESET on pin 7; suitable for µPs (e.g. Intel 80C51) requiring active-HIGH reset. Guaranteed valid with VCC down to 1.1V. |
