HM514260C, HM51S4260C Series
Notes concerning 2CAS control
Please do not separate the UCAS/LCAS operation timing intentionally. However skew between
UCAS/LCAS are allowed under the following conditions.
(1) Each of the UCAS/LCAS should satisfy the timing specifications individually.
(2) Different operation mode for upper/lower byte is not allowed; such as following.
(3) Closely separated upper/lower byte control is not allowed. However when the condition (tCP ≤ tUL) is
satisfied, fast page mode can be performed.
