TMP86FM29

Note 2: The 86FM29 can not drive the 5V LCD panel because the electrical characteristics in 86FM29 is

altered from 86C829B/H29B/M29B/PM29A/PM29B/C929AXB. The recommended operating

condition of V3 pin in TMP86FM29 is 3.6V(max). For details, refer to “Electrical Characteristics”.

When the LCD booster circuit is used in 86FM29, connect the reference voltage and capacitor as

shown in "case2". Though the method of "case1" has been recommended in 86C829B

/H29B/M29B/PM29A/PM29B datasheets, the 86FM29 should not use method of "case1". Even if the

method of "case1" is used in the 86C829B/H29B/M29B/PM29A/PM29B/C929AXB, the function and

operation are not issue at all. However, if the "case2" is used, the booster ability becomes higher

than "case1". Therefore, when the application board is designed newly in future, the method of

"case2" is also recommended in 86C829B/H29B/M29B/PM29A/PM29B/C929AXB.

Note 3: Flash function, CPU wait period and serial PROM mode cannot be emulated in the 86C929AXB. If

the software including the flash function is executed in 86C929AXB, the operation process differs

from 86FM29.
