A Microcontroller Interface for Embedded Non-volatile Memory on Micro Mirror Projector ASIC Calibration
Keywords:
Microcontroller, non-volatile memory (NVM), micro mirror projection, micro-electro-mechanical systems (MEMS).Abstract
This paper presents a digital controller interface
for an non-volatile memory (NVM) IP [1] which is part of an
embedded 8051 microprocessor system. The embedded
microprocessor system is targeted to be integrated as part of a
micro mirror projection ASIC for MEMS scanner control and
sensing [2]. The NVM memory controller interface with the
storage of NVM is used to calibrate the position of micro mirror
MEMS on the fly during the projection scanning mode, and
store and load the configuration parameters for ASIC module
initialization during power up stage. The design has been
fabricated with 0.18 µm CMOS process and measurement
result proves the full function of the design concept.
