s DIFFERENCES AMONG PRODUCTS

1. Memory Size

Before evaluating using the OTP product, verify its differences from the product that will actually be used.

2. Current Consumption

When operated at low speeds, a product mounted with either one-time PROM or EPROM consumes more

current than a product mounted with a mask ROM. However, in sleep/stop mode the current consumption is the

same.

For detailed information on each package, see “s PACKAGE DIMENSIONS.”

3. Differences Between the MB89590B series and the MB89590BW Series

MB89590B series : Remains in high impedance state until USB connection takes place. Before the USB

connection, use one general-purpose port output to control pullup resistance connec-

tion of this port by software.

MB89590BW series : Outputs at low level until USB connection takes place.
