• Manufacturer: CORERIVER Semiconductor

1 Product Overview
CORERIVER’s MiDAS1.0 family is a group of fast 80C52 compatible microcontrollers without wasted
clock and memory cycles. Four clocks per one machine cycle are consumed in the redesigned processor
core of the MiDAS 1.0 Family. As a result, all its 8052 instruction is executed about 3 times faster than
that of traditional 80C52.
The MiDAS1.0 family offers three timer/counters, a serial port, maximum 36 I/O ports, four-channel 9-bit
ADC (Analog to Digital Converter), two-channel 8-bit PWM (Pulse Width Modulator), a Watchdog timer,
and LVD (Low Voltage Detector) as peripherals.
The MiDAS1.0 family provides power saving modes for the power-critical applications and also does
noise tolerant scheme.
To help a user develop a target system, user-friendly MDS (MCU Development System) called as
GENSYS and an easy-to-use training kit is also provided.
