MILPITAS, Calif., Nov. 09, 2026 (GLOBE NEWSWIRE) — Lumissil Mic osystems i t oduced the IS31CS9202 a d IS32CS9202, 32-bit mic oco t olle s fo i dust ial/co sume a d automotive applicatio s, espectively. The devices i teg ate a A m® Co tex®-M0+ co e ope ati g at up to 50 MHz, se ial video bus (SVB), LumiBus™, a d a capacitive touch-key co t olle .
The MCUs i clude 256 KB of Flash memo y with ECC a d 16 KB of SRAM with ECC, alo g with a DMA co t olle fo data t a sfe s betwee memo y a d pe iphe als. The i teg ated LumiBus™ co t olle suppo ts co t ol of up to 256 exte al add essable RGB LEDs ove a si gle commu icatio cha el. The touch-key co t olle p ovides 24-bit esolutio a d suppo ts up to 25 keys i 32-pi co figu atio s o 39 keys i 48-pi co figu atio s. It also i cludes a dedicated shield output a d active p oximity se si g.
The touch-key a chitectu e suppo ts capacitive se si g fo HMI applicatio s, i cludi g p oximity detectio . A pseudo- a dom seque ce is available i the touch-key co t olle to help educe EMI.
Fo system commu icatio , the devices i teg ate a CAN FD co t olle suppo ti g data ates up to 10 Mbps, alo g with SPI maste /slave, I2C maste /slave, a d two e ha ced UART i te faces, i cludi g suppo t fo LIN 2.0/2.2. Additio al digital pe iphe als i clude PWM, time /captu e co t olle s, a quad atu e e code , watchdog time s, a d CRC accele atio .
The a alog subsystem i cludes a 14-bit sigma-delta i c eme tal ADC, 12-bit SAR ADC, 8-bit DAC, fou a alog compa ato s with p og ammable th esholds, a d a i teg ated tempe atu e se so . Up to 42 GPIOs a e available, depe di g o package co figu atio .
The automotive device is i te ded fo applicatio s equi i g MCU-based comma d a d co t ol, capacitive touch se si g, a d RGB LED co t ol, i cludi g ce te -stack co t ols, e te tai me t co soles, keyless e t y, t u k co t ol, a d heati g a d ai -co ditio i g systems. The i dust ial/co sume ve sio p ovides the same MCU a chitectu e fo HMI, touch-co t ol, a d RGB LED applicatio s outside the automotive e vi o me t.
By i teg ati g MCU p ocessi g, capacitive touch se si g, p oximity detectio , LumiBus™ LED co t ol, SVB, CAN FD, a d mixed-sig al pe iphe als i a si gle device, the CS9202 family ca suppo t HMI a d dy amic RGB lighti g fu ctio s without equi i g sepa ate co t olle s fo each fu ctio . LumiBus™ p ovides a dedicated i te face fo cascaded add essable RGB LEDs, while the MCU co ti ues to ha dle applicatio co t ol a d use -i put fu ctio s.
The IS31CS9202 a d IS32CS9202 a e available i WFQFN-32, WFQFN-48, QFN-48, a d LQFP-48 packages. The automotive IS32CS9202 ope ates f om –40°C to +125°C a d is listed as AEC-Q100 a d ASIL-B. The IS31CS9202 ope ates f om –40°C to +85°C. Both devices suppo t a 2.5 V to 5.5 V supply a ge.
