The AT21CS01-SSHM10-B is a one-time programmable nonvolatile memory, engineered to provide reliable and efficient storage of user data or instructions. With a large storage capacity of 1 Mbit, it is capable of storing large amounts of user data, without any risks of data loss due to power or environmental changes. The device is manufactured using advanced CMOS process technology and is supplied in a tiny 9mm x 20mm package, resulting in a low-profile, small-footprint memory solution.

The AT21CS01-SSHM10-B is a reprogrammable flash memory that is ideal for applications requiring frequent configurations. It is available in two power supply options: a 5V single-ended option and a 3.3V single-ended option. The device includes two SPI interfaces, an 8-bit bus and a 4-bit bus, which enables it to be used as either a single-ended or a dual-bus architecture. As the power supply voltage of each interface can vary independently, the device is also suitable for implementations with a shared power source.

The 8-bit bus can be configured to operate in either serial or byte-wide modes. In byte-wide mode, the data is organized into four bytes of 1024 bits each. The 4-bit bus is operable in both serial and parallel modes. In the parallel mode, the data is organized into 512 bytes of 8 bits each. In either mode, the AT21CS01-SSHM10-B allows up to eight separate nonvolatile areas to be defined within the device.

The AT21CS01-SSHM10-B also features an on-chip power-on reset circuit, which provides protection against power surges. Additionally, the device employs a unique data retention mechanism that helps ensure reliable data storage during power cycles. The on-chip sleep mode allows the device to reduce its active power consumption to less than 10uA. This makes it ideal for use in battery-powered applications.

The AT21CS01-SSHM10-B provides a number of applications and features which make it ideal for use in embedded systems. One of its main features is that it can be used to store boot code, which is ideal for applications where frequent updates to the firmware are required. It is also widely used for remote device configuration and management, as it provides an easy and efficient way to store, update and maintain user data. Additionally, the device can be used for secure code storage in automotive applications, thanks to its advanced on-chip security circuitry.

In summary, the AT21CS01-SSHM10-B is a reliable and efficient nonvolatile memory that provides a secure and convenient way of storing and managing user data. Its various features and powerful architectures make it ideal for use in embedded and automotive applications, allowing users to efficiently store, access and update important data. Furthermore, its advanced security circuitry and power-on reset circuit guarantees data integrity in the event of a power surge or loss of power. This ensures that the stored data remains safe even after a power cycle.
