P2ROM MultiMediaCard
1/24
1. GENERAL
DESCRIPTION
P2ROM MMC stands for P2ROM MultiMediaCard in which an Oki Original Product P2ROM is embedded.
P2ROM (Production Programmed ROM) utilizes Oki unique memory cell, which is an exclusive Oki technology.
Unlike MASKROM, no mask charges apply; Unlike OTP and Flash memory, no additional programming cost is
required.
Features
Compliant with MMCA standard (Version 3.1)
Card name/capacity
1MB P2ROM MMC: MR57T00101F-xxxKB
Operating voltage: 2.7V~3.6V
Outside dimension: 32(D)
24(W)1.4(H)mm
Notice
This product is different from Secure MMC.
Applications
P2ROM MMC is applied to devices embedded with MultiMediaCard Slot, e.g. Mobile phone,
Electronic dictionary, Game machine, etc.

Argument

0 GO_IDLE_STATE
Resets all cards to Idle
state.
When CS signal is set in
Low state, the card transits
to SPI mode after receiving
this command.

SEND_OP_COND
Asks the card to send an R3
response including OCR
data. The operation voltage
span of the card can be got
according to OCR data.
Moreover, the highest-order
1 bit of OCR is used to
check whether the internal
processing of the card is
finished or not (Ready /Busy
polling).

R3 None

ALL_SEND_CID
Asks the cards in Ready
state to send their CID
numbers.
The numbers are sent to
CMD signal when the card
is in MMC mode. When
every 1 bit is transferred,
the CMD signal state is
compared with the state
within the card. If different,
data transmission stops,
and the card returns to
Ready state. If matched, the
card recognizes itself
selected and transits to
Identification state.

SET_RELATIVE_ADDR Assigns Relative Card
Address (RCA) to the card
in Identification state.
When RCA is assigned, the
card transits to Stand-by
state, and does not
respond to following CMD2
& CMD3.

DESELECT_CARD
Selects a card and toggles
it between the Stand-by and
Transfer states.
When given an assigned
RCA, the card transits from
Stand-by state to Transfer
state, and responds to the
following read and other
commands. When given an
unassigned RCA, the card
transits to Stand-by state.
When RCA=0000h, the
card transits to Stand-by
state unconditionally.

9. POWER
UP
Power up sequence is shown below.
Circuit for detecting power-supply voltage is embedded in this MMC. When the voltage is below a certain value,
power-on reset is generated in order to prevent operation error. As long as enough voltage is reached, the internal
initialization is done automatically.

10. SHORTCUT PROTECTION
Cards shall be inserted/removed into/from the bus without damage. If one of the supply pins (VDD or VSS) is not
connected properly, then the current is drawn through a command line or a data line. In such case, the card cannot
work normally.
The device connector for P2ROM MMC insertion should be connected as following steps, for the length of contact
pins is different (length of VSS, VDD > length of other signals).
Step-1: VSS (pin 3), VDD (pin 4) connection
Step-2: Other signals (pin 1~2, 5~7) connection
