2. Flash Memory
The Pm39LV010R is a 1 Megabit, 3.3 Volt-only Flash Memory organized as 131,072 bytes of 8 bits each. This device
is designed to use a 3.0 Volt to 3.6 Volt power supply to perform in-system programming.
The 1 Megabit memory array is divided into thirty-two uniform blocks of 4 Kbytes each for data and/or code storage.
The block architecture allows users to flexibly make chip erase or block erase operation. The block erase feature
allows a particular block to be erased and reprogrammed without affecting the data in other blocks. After the device
performs chip erase or block erase operation, it can be reprogrammed on a byte-by-byte basis.
3. GM5120
The gm5110/20 is a graphic processing IC for Liquid Crystal Display (LCD) monitors at XGA/SXGA resolution. It
provides all key IC functions required for the highest quality LCD monitors. On-chip functions include a high-speed
TM
triple-ADC and PLL, Ultra-Reliable DVI receiver, a high quality zoom and shrink scaling engine, an on-screen
display (OSD) controller, digital color controls and an on-chip microcontroller (OCM). With this level of integration,
the gm5110/20 devices simplify and reduce the cost of LCD monitors while maintaining a high-degree of flexibility and
quality.
