OKI Semiconductor
ML66525 Family
16-Bit Microcontroller
FEDL66525-02
Issue Date: July 19, 2002
GENERAL DESCRIPTION
The ML66525 family devices are high-performance 16-bit CMOS microcontrollers that utilize the nX-8/500S,
Oki鈥檚 proprietary CPU core.
Data from a personal computer with a USB connector can be automatically, quickly written or read to and from
NAND type Flash Memory via USB I/F and NAND Flash Memory I/F.
The ML66525 family devices support clock gear functions, a sub-clock and HALT/STOP mode, which are
suitable for low power applications.
The ML66525 family devices are provided with interfaces to external devices such as a 4-channel multi-functional
serial interface with internal 32-byte FIFO and a high-speed bus interface that has separate address and data buses
and does not require external address latches.
A wide variety of internal multi-functional timers enable various timing controls such as periodic and timed
measurements.
With a 16-bit CPU core that enables high-speed arithmetic computations and a variety of bit processing functions,
these general-purpose microcontrollers are optimally suited for Digital Audio devices such as MP3 players, voice
recorders, handy games, and PC peripheral control systems (to control devices that can be connected to USB and
store data into memory).
The ML66525 family devices also include the flash ROM version device (ML66Q525B) that is programmable
with a single 3 V power supply (2.4 to 3.6 V).
[ Note ] ML66525A/ML66Q525A are supplied as stock lasts.
