P2ROM ADVANCED TECHNOLOGY
P2ROM stands for Production Programmed ROM. This exclusive LAPIS Semiconductor technology utilizes
factory test equipment for programming the customers code into the P2ROM prior to final production testing.
Advancements in this technology allows production costs to be equivalent to MASKROM and has many
advantages and added benefits over the other non-volatile technologies, which include the following;
· Short lead time, since the P2ROM is programmed at the final stage of the production process, a large P2ROM
inventory "bank system" of un-programmed packaged products are maintained to provide an aggressive
lead-time and minimize liability as a custom product.
· No mask charge, since P2ROMs do not utilize a custom mask for storing customer code, no mask charges
apply.
· No additional programming charge, unlike Flash and OTP that require additional programming and handling
costs, the P2ROM already has the code loaded at the factory with minimal effect on the production throughput.
The cost is included in the unit price.
· Custom Marking is available at no additional charge.
· Pin Compatible with Mask ROM and some FLASH products.

Notes for Mounting the Surface Mount Type Package
The surface mount type packages are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact ROHM’s responsible sales person for the product name,
package name, pin number, package code and desired mounting conditions (reflow method, temperature and
times).
