One-time PROM built-in 8-bit Single Chip Microcontroller

SANYO -> Panasonic 

LC86P4332

Requirements Prior to Mounting

Notes on Handling

• The construction of one-time microcontrollers in which the PROM is not programmed precludes Sanyo from fully testing them

before they are shipped. The screening procedure described below is recommended in order to attain higher reliability after

programming the PROM.

• The nature of one-time microcontrollers in which the PROM is not programmed precludes us from fully testing them by writing

all of the bits. Therefore, it is not possible for us to guarantee a write yield of 100%.

• Storage in moisture-proof packaging (unopened)

While they are still in the moisture-proof packaging, these devices should be stored at a temperature of 30˚C and a humidity of

no more than 70%.

• After opening the moisture-proof packaging

These devices should be mounted and soldered as soon as possible after the moisture-proof packaging is opened. Once the

moisture-proof packaging is opened, the devices should be stored at a temperature of 30˚C and a humidity of no more than 70%

for no more than 96 hours.
