AKCP903201

Programmable Power Sequencer IC

The AKCP903201 device incorprates the ARM® Cortex®-M23 32-bit processor core operating at up to72MHz up up to 72 MHz frequency with Flash accesses 0~2 wait states to obtain maximum efficiency.

It provides up to 64 KB embedded Flash memory and up to 8 KB SRAM memory. An extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer one 12-bit ADC and one comparator, up to five general 16-bit timers, a basic timer, a PWM advanced timer, as well as standard and advanced communication interfaces: up to two SPIs, two I2Cs, two USARTs, and an I2S.

The device operates from a 1.8 to 3.6 V power supply and available in –40 to +85 °C temperature range for grade 6 devices, and -40°C to +105°C temperature range for grade 7 devices. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications.

ARM® Cortex®-M23 core

The Cortex-M23 processor is an energy-efficient processor with a very low gate count. It is intended to be used for microcontroller and deeply embedded applications that require an area-optimized processor. The processor is highly configurable enabling a wide range of implementations from those requiring memory protection to cost sensitive devices requiring minimal area, while delivering outstanding computational performance and an advanced system response to interrupts.
