Preliminary Specifications Rev. 0.9

Specifications in this manual are tentative and subject to change.

Table 1.18.5. Flash memory version electrical characteristics

(referenced to VCC = 5.0V, at Topr = 25oC, unless otherwise specified)

Table 1.18.4. A-D conversion characteristics (Notes 1–3)

LSB

AN0 to AN7 input

Note 2: AD operation clock frequency (ØAD frequency) must be 10 MHz or less. And divide the fAD if VCC is less than 4.2V,

and make ØAD frequency equal to or lower than fAD/2.

Note 3: When not using sample & hold function, ØAD frequency must be

≥ 250 kHz, but less than the upper limit set by Note 2.

When using sample & hold function, ØAD frequency must be

≥ 1MHz, but less than the upper limit set by Note 2.
