Overview
Maximize battery life, measure more precisely
and make development easier with Freescale’s
MC9S08LH64/36. The 16-bit SAR delivers
outstanding precision to meet the needs of
entry-level metering and medical applications.
Cost is reduced with the integration of an
LCD driver which supports more segments
with fewer pins. Additionally, the MCU is
the industry’s best-in-class ultra-low-power
MCU with LCD for long operation in battery-
powered applications. These features are ideal
for smart metering and medical applications
such as glucometers and pulse oximeters.
Provides entry level flash-size part (64 KB)
for cost-conscious, single-phase, electricity
meter designs. The enhanced ADC, along with
low-power technology, is ideal for electricity
meters and medical devices operated by
battery for more than five years.
Smart metering and medical design made easy
