— Full high: all units fully powered at high clock frequency
— Full low: all units fully powered at low clock frequency
— Doze: core functional units disabled except time base, decrementer, PLL,
memory controller, real-time clock, and CPM in low-power standby
— Sleep: all units disabled except real-time clock and periodic interrupt timer. PLL
is active for fast wake-up
— Deep sleep: all units disabled including PLL, except the real-time clock and
periodic interrupt timer
— Low-power stop: to provide lower power dissipation
— Separate power supply input to operate internal logic at 2.2 V when operating at
or below 25 MHz
— Can be dynamically shifted between high frequency (3.3 V internal) and low
frequency (2.2 V internal) operation
Debug interface
— Eight comparators: four operate on instruction address, two operate on data
address, and two operate on data
— The MPC850 can compare using the =,
≠
, <, and > conditions to generate
watchpoints
— Each watchpoint can generate a breakpoint internally
3.3-V operation with 5-V TTL compatibility on all general purpose I/O pins.
Part III Electrical and Thermal
Characteristics
This section provides the AC and DC electrical specifications and thermal characteristics
for the MPC850. Table 3-2 provides the maximum ratings.
