PRELIMINARY
MX53L03200
ROM MultiMediaCard
1.General Description
The MultiMediaCard MX53L03200 is a highly integrated read only memory (ROM) with serial and random access capability using an innovative ultra high density cell design in the memory array. It is accessible via a dedicated serial interface optimized for fast and reliable data transmis-sion. This interface allows several cards to be stacked by through connecting their peripheral contacts. The MX53L03200 is fully compatible to a new consumer standard, called the MultiMediaCard system s t a n d a r d defined in the MultiMediaCard system specification [1]. The MultiMediaCard system is a new mass-storage s y s t e m based on innovations in semiconductor technology. It has been developed to provide an inexpensive, mechanically robust storage medium in card form for multimedia consumer applications. MultiMediaCard allows the design of inexpensive players a n d drives without moving parts. A low power consumption and a wide supply voltage range favors mobile, battery-powered applications such as audio p l a y e r s , organizers, palmtops, electronic books, encyclopedia and dictionaries. Using very effective data c o m p r e s s i o n schemes such as MPEG, the MultiMediaCard will deliver enough capacity for all kinds of multimedia data: software/programs, text, music, speech, images, video etc.

Figure 1 : MX53L03200 architecture All controllers in the MX53L03200 are clocked by the interface signal CLK. The card is controlled by the three line MultiMediaCard interface containing the signals: CMD, CLK, DAT (see "Chapter 4: Inter-face" for more details). For the identification of the MX53L03200 in a stack of MultiMediaCards a card identification register (CID) and a relative card address register (RCA) is foreseen. An additional register contains different types of operation parameters. This register is called card specific data register (CSD). The communication using the MultiMediaCard lines to access either the memory field or the registers is defined by the MultiMediaCard standard (see "Chapter 6: Communication"). The card has its own power on detection unit. No additional master reset signal is required to setup the card after power on. It is protected against shortcut during insertion and removal while the Multi-MediaCard system is powered up (see "Chapter 9: Power supply").

4. INTERFACE
In the MX53L03200 all data is transferred over a minimal number of lines: · CLK: with each cycle of this signal a one bit transfer on the command and data lines is done. The frequency may vary between zero and the maximum clock frequency. The MultiMediaCard bus master is free to generate these cycles without restrictions in the range of 0-20MHz. · CMD: is a bidirectional command channel used for card initialization and data transfer commands. The CMD signal has two operation modes: open drain for initialization mode and push pull for fast command transfer. Commands are sent from the MultiMediaCard bus master to the MX53L03200 and responses vice versa. · DAT: is a data channel with a width of one line. The DAT signal of the MX53L03200 operates in push pull mode.
