MX10FMAXDQC
SINGLE-CHIP 8-BIT MICROCONTROLLER
• Code protection
• Two priority levels
• Power saving Idle and power down modes
• 64 K external program memory space
• 64 K external data memory space
• Four 8-bit I/O ports
• Full-duplex enhanced UART compatible with the stan-
dard 80C51 and the 80C52
GENERAL DESCRIPTION
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 architecture, 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 output, and up/down
counting capabilities such as motor control. It also has a more versatile serial channel that facilitates multi-processor
communications.

IDLE MODE
The user's software can invoke the Idle Mode. When the microcontroller is in this mode, power consumption is
reduced. The Special Function Registers and the onboard RAM retain their values during Idle, but the processor
stops executing instructions. Idle Mode will be exited if the chip is reset or if an enabled interrupt occurs.

POWER DOWN MODE
To save even more power, a Power Down mode can be invoked by software. If this mode, the oscillator is stopped and
the instruction that invoked Power Down is the last instruction executed. The on-chip RAM and Special Function
Registers retain their values until the Power Down mode is terminated.
On the MX10C805X either a hardware reset or an external interrupt can cause an exit from Power Down. Reset
redefines all the SFRs but does not change the on-chip RAM. An external interrupt allows both the SFRs and on-chip
RAM to retain their values.
To properly terminate Power Down, the reset or external interrupt should not be executed before VCC is restored to its
normal operating level, and must be held active long enough for the oscillator to restart and stabilize (normally less
than 10 ms).
With an external interrupt, INT0 and INT1 must be enabled and configured as level-sensitive. Holding the pin low
restarts the oscillator but bringing the pin back high completes the exit. Once the interrupt is serviced, the next
instruction to be executed after RETI will be the one following the instruction that put the device into Power Down.
