ABSOLUTE MAXIMUM RATINGS

Stresses greater than those listed in Table 17 may cause perma-

nent damage to the device. These are stress ratings only.

Functional operation of the device at these or any other condi-

tions greater than those indicated in the operational sections of

this specification is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect device

reliability.

When programming OTP memory on the ADSP-BF51x proces-

sor, the V

PPOTP pin/ball must be set to the write value specified in

the Operating Conditions on Page 20. There is a finite amount

of cumulative time that the write voltage may be applied

(dependent on voltage and junction temperature) to V

PPOTP over

the lifetime of the part. Therefore, maximum OTP memory pro-

gramming time for the processor is shown in Table 19.

Table 20 and Table 21 specify the maximum total source/sink

(IOH/IOL) current for a group of pins. Permanent damage can

occur if this value is exceeded. To understand this specification,

if pins PF9, PF8, PF7, PF6, and PF5 from Group 1 in Table 21

table were sourcing or sinking 2 mA each, the total current for

those pins would be 10 mA. This would allow up to 70 mA total

that could be sourced or sunk by the remaining pins in the

group without damaging the device. Note that the VOH and VOL

specifications have separate per-pin maximum current require-

ments as shown in the Electrical Characteristics table.

VIN Min (V)

2 The individual values cannot be combined for analysis of a single instance of

overshoot or undershoot. The worst case observed value must fall within one of

the voltages specified and the total duration of the overshoot or undershoot

(exceeding the 100% case) must be less than or equal to the corresponding duty

cycle.

VIN Max (V)

Maximum Duty Cycle3

3 Duty cycle refers to the percentage of time the signal exceeds the value for the

100% case. The is equivalent to the measured duration of a single instance of

overshoot or undershoot as a percentage of the period of occurrence.
