What is the battery life of the ICP2-Portable(G3)?
Answer
Battery life estimation is complex, as it depends on various operating conditions. However, under typical use, the ICP2-Portable (G3) provides sufficient capacity for more than 1,000 programming cycles.
The following examples illustrate the approximate number of programming cycles achievable using alkaline batteries (assumed conditions: 30 seconds of idle time per cycle, battery capacity 2500 mAh):
Best case (5 s programming):No load, Vdd = Vpp = 3.3 V → approximately 3,000 cycles
Worst case (5 s programming):Vdd = 5 V, Vdd current = 40 mA (load = 120 Ω); Vpp = 13 V, Vpp current = 13 mA (load = 1 kΩ) → approximately 1,600 cycles
Large devices (≥ 256 KB, programming time ≈ 30 s):Powered from 3.3 V, resulting in about 1,000 cycles under worst-case conditions
