M58WRxxxKU, M58WRxxxKL
Description
The M58WR016KU/L and M58WR032KU/L are 16-Mbit (1 Mbit ×16) and 32- Mbit (2 Mbit
×16) non-volatile Flash memories, respectively. In the rest of the document, they will be
referred to as M58WRxxxKU/L unless otherwise specified.
The M58WRxxxKU/L may be erased electrically at block level and programmed in-system
on a word-by-word basis using a 1.7 V to 2 V VDD supply for the circuitry and a 1.7 V to 2 V
VDDQ supply for the Input/Output pins. An optional 9 V VPP power supply is provided to
speed up customer programming.
The first sixteen address lines are multiplexed with the Data Input/Output signals on the
multiplexed address/data bus ADQ0-ADQ15. The remaining address lines, A16-Amax, are
the Most Significant Bit addresses.
The device features an asymmetrical block architecture:
●
the M58WR016KU/L have an array of 39 blocks, and are divided into 4 Mbit banks.
There are 3 banks each containing 8 main blocks of 32 KWords, and one parameter
bank containing 8 parameter blocks of 4 KWords and 7 main blocks of 32 KWords.
●
the M58WR032KU/L have an array of 71 blocks, and are divided into 4 Mbit banks.
There are 7 banks each containing 8 main blocks of 32 KWords, and one parameter
bank containing 8 parameter blocks of 4 KWords and 7 main blocks of 32 KWords
The Multiple Bank Architecture allows Dual Operations, while programming or erasing in
one bank, Read operations are possible in other banks. Only one bank at a time is allowed
to be in Program or Erase mode. It is possible to perform burst reads that cross bank
boundaries. The Parameter Blocks are located at the top of the memory address space for
the M58WR016KU and M58WR032KU, and at the bottom for the M58WR016KL and
M58WR032KL.
Each block can be erased separately. Erase can be suspended, in order to perform program
in any other block, and then resumed. Program can be suspended to read data in any other
block and then resumed. Each block can be programmed and erased over 100 000 cycles
using the supply voltage VDD. There are two Enhanced Factory programming commands
available to speed up programming.
Program and Erase commands are written to the Command Interface of the memory. An
internal Program/Erase Controller takes care of the timings necessary for program and
erase operations. The end of a program or erase operation can be detected and any error
conditions identified in the Status Register. The command set required to control the
memory is consistent with JEDEC standards.
The device supports synchronous burst read and asynchronous read from all blocks of the
memory array; at power-up the device is configured for asynchronous read. In synchronous
burst mode, data is output on each clock cycle at frequencies of up to 86 MHz. The
synchronous burst read operation can be suspended and resumed.

M58WRxxxKU, M58WRxxxKL
Description
The device features an Automatic Standby mode. When the bus is inactive during
Asynchronous Read operations, the device automatically switches to the Automatic Standby
mode. In this condition the power consumption is reduced to the standby value IDD4 and the
outputs are still driven.
The M58WRxxxKU/L features an instant, individual block locking scheme that allows any
block to be locked or unlocked with no latency, enabling instant code and data protection. All
blocks have three levels of protection. They can be locked and locked-down individually
preventing any accidental programming or erasure. There is an additional hardware
protection against program and erase. When VPP ≤VPPLK all blocks are protected against
program or erase. All blocks are locked at Power-Up.
The device includes a Protection Register to increase the protection of a system’s design.
The Protection Register is divided into two segments: a 64 bit segment containing a unique
device number written by ST, and a 128 bit segment One-Time-Programmable (OTP) by the
user. The user programmable segment can be permanently protected.
The memory is available in a VFBGA44 7.5 × 5 mm, 10 × 4 active ball array, 0.5 mm pitch
package. It is supplied with all the bits erased (set to ’1’).
