MX10C805X Datasheet, PDF (1/14 Pages) Macronix International – SINGLE-CHIP 8-BIT MICROCONTROLLER

ADVANCED INFORMATION
MX10C805X
SINGLE-CHIP 8-BIT MICROCONTROLLER
FEATURE
• High performance CMOS ROM CPU
• Operation Voltage 5V
• Up to 40MHz operation (3.5MHz to 40MHz)
• Three 16-bit timer/counters
• 256 Bytes of on-chip data RAM
• 4/8/16/32/64 Kbytes on-chip Program memory
• 32 Programmable I/O lines
• On-chip Watch-Dog-Timer (WDT)
• 6 interrupt Sources
GENERAL DESCRIPTION
• ROM Code protection
• Two priority levels
• Power saving Idle and power down modes
• 64 K external program memory space
• 64 K external data memory space
• Available in PLCC, PQFP, and PDIP package
• Four 8-bit I/O ports
• Full-duplex enhanced UART compatible with the stan-
dard 80C51 and the 80C52
• Extended Temperature Range (-40°C to +85° C)
The single-chip 8-bit microcontroller is manufactured in
MXIC's advanced CMOS process. This device uses the
same powerful instruction set, has the same architec-
ture, and is pin-to-pin compatible with the existing 80C51.
The added features make it an even more powerful
microcontroller for applications that require clock out-
put, and up/down counting capabilities such as motor
control. It also has a more versatile serial channel that
facilitates multi-processor communications.
