SEIKO S809

The Maxim/Dallas pin-compatible alternative to the S809 is the MAX6424/MAX6425 Low-Power, SC70/SOT µP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay.

Benefits of the MAX6424/MAX6425 microprocessor over the S809:

• Reset threshold accuracy (±1.5% vs. ±2%)
• Typical reset threshold tempco (20ppm/C vs. 190ppm/C)
• Specifications guaranteed temperature range (-40°C to 125°C vs. 25°C)

Benefits of the S809 microprocessor over the MAX6424/MAX6425:

• Lower supply current (1.2µA vs. 2.0µA at Vcc = 3.3V)
• Wider operating voltage range (0.7V-10V vs. 1.0V-5.5V)
