Notes •The QFP packages should be heat-soaked for 12 hours at 125°C immediately prior to mounting (This baking is called pre-baking).
          •After pre-baking a controlled environment must be maintained until soldering. The environment must be held at a temperature of 30°C or less and a humidity level of 70% or less. Please solder within 24 hours.

Description

The LC86E7148 is a CMOS 8-bit single chip microcontroller with UVEPROM for the LC867100 series. This microcontroller has the function and the pin description of the LC867100 series mask ROM version, and 48K-byte EPROM.
